What did ancient languages sound like?

In 1878, a student called Ferdinand de Saussure proposed that PIE had only one vowel sound "e", and that all other vowel sounds in PIE languages came that single sound. How? He proposed that all other vowels came through a consonant "colouring" the original vowel "e". For example, the usage of e + w in words gave birth to the sound "u".
But this doesn't explain root words like "pas" that don't contain the core vowel "e" or any evidence of a rogue sound like "w" colouring it.
Here I will quote from the book: "Saussure conjured up a daring hypothesis. Once upon a time, he argued, verbs like pas did indeed have a rogue sound after the core vowel e, and this sound was responsible for 'colouring' the vowel from e to a. But at a later stage, and after it had wreaked all this havoc, the rogue sound disappeared from the scene. If one were to use the symbol X to represent this elusive rogue sound, then Saussure's claim was that pas originated as a regular root peXs, but that some time in prehistory X coloured the vowel e into an a, so peXs became paXs. Much later on (but still well before the earliest records), the rogue X was itself worn away because of [some other changes]. Schematically, then, the whole development can be represented as peXs -> paXs -> pas."
This remained a cool theory, outside mainstream linguistics. Then after Saussure died, archaeologists dug up some tablets and the oldest PIE language Hittite was deciphered. And there appearing in the very place where he had predicted it to be, the rogue consonant was found written down in clay.

That's not in perfect agreement with wiki:
> The beginnings of the [laryngeal] theory were proposed by Ferdinand de Saussure in 1879, in an article chiefly demonstrating that a and o were separate phonemes in PIE.
And: > In the course of his analysis, Saussure proposed that what had then been reconstructed as long vowels ā and ō, alternating with ǝ, was an ordinary type of PIE ablaut. That is, it was an alternation between e grade and zero grade like in "regular" ablaut (further explanations below), but followed by a previously unidentified element. This element accounted for both the changed vowel colour and the lengthening (short e becoming long ā or ō).
The catch is that so-called laryngeals where they reflect in Hittite with Cuniform Characters like Ha and similar only in front of a word and only for two of three or more, meaning there is still no direct evidence of * paXs, or peh2s-, ph2es- depending on voewl length, modulo accentuation. Ah yeah, there are mostly three now.
Other topolects such as Cantonese preserved them, which makes it a better correspondence if you care about hearing something closer to the Middle Chinese that Tang poetry was composed in.
How do we know so much about Middle Chinese pronunciation in the present day? Check out https://www.youtube.com/watch?v=ME8wzyR6pO8 for a layperson's introduction.
Classical Chinese scholarship had a developed body of proto-linguistics, including rime spelling, a system for phonetic transcription and analysis, which transcribed sounds using Chinese characters purely phonetically. It was used to indicate the pronunciation of characters, as well as foreign words in bilingual dictionaries and so on: https://en.wikipedia.org/wiki/Fanqie
The problem is, it's mostly self-referential. As the Wikipedia example gives, we don't precisely know how 東 was pronounced in 1000 AD from a fanqie dictionary entry. It would tell us something like that 東 (dong1 in Mandarin or dung1 in Cantonese today) was pronounced in the author's time like the initial consonant in 德 (de2, dak) with a closing syllable pronounced like 紅 (hong2, hung4). And of course, a dictionary from a thousand years before that, or even just from a speaker on the other side of China, might give a different entry...
If you collect all the known fanqie pronunciations given in all the eras from all the probable sister languages, and especially when you start comparing with our knowledge of other languages (Japanese, Sanskrit, etc.) you can start to piece together the puzzle and get a rather good understanding of Chinese historical sound change.
Chinese scholars back then were aware, on some level, of sound change, especially later in the Ming and Qing dynasties, but there was no general theory to address it, and the apparent contradictions in the ancient poetry and the old rime dictionaries were a source of a lot of perplexity.
It would make sense then if there was much earlier linguistics / folk etymologist, etc. in Chinese history. Whereas I didn't think think anything like modern linguistics got going until the enlightenment creation of the Classics' modern form.
According to https://en.wikipedia.org/wiki/Lion-Eating_Poet_in_the_Stone_..., the poem was written by a linguist, so I don't think it it is representative of how most later writers of Literary Chinese thought pronunciation ought to work, but rather a reductio ad absurdum argument again writing in dead languages without using an alphabet.
I realize topolect is a translation of an official chinese term, but as far as I'm aware we're not Chinese officials. We're speaking English, and we can be brave enough to call mutually unintelligible languages what they are - languages.
And before anyone gives me the 'language is a dialect with an army and a navy' - yes it's pithy but there's so many counter examples.
I'm not super familiar with the specifics of Mandarin, so I could be wrong here, but it's quite common to come across English words that have fallen out of common use by native speakers but are adopted by non-native speakers as a vehicle for expressing a concept that exists in their native language but doesn't have a precise translation into English.
Especially since they're talking about the evolution of Chinese pronunciation, "topolect", while jargon-y, seems to be a far more precise vehicle for expressing their sentiment.
https://en.wiktionary.org/wiki/topolect
http://sino-platonic.org/complete/spp029_chinese_dialect.pdf
It's a way to take 方言 and decouple it from linguistic terms like language and dialects so a proper study and classification of the Chinese language family and its various languages and dialects can take place without interference from Chinese politics. When someone points out that Cantonese, Hokkien, and Mandarin are 方言 then linguists can nod politely, agree that they are in fact "topolects", then continue classifying them as Sinitic languages within the Sino-Tibetan language family each with their own collection of dialects.
Would be interesting to know if the study of Arabic has similar issues because from a layman's cursory knowledge Arabic has similar diversity when it comes to mutual intelligibility.
On a side note, I actually found it a little bit ironic that Afrikaans was listed as a dialect of Dutch in his paper.
Many South Africans would disagree with that classification quite strongly, especially since Afrikaans has its own literature and regional dialects.
In turn, there's a movement to classify the coloured dialect of Afrikaans as its own language (Kaaps), in fear that it will be swallowed up by the more standard "white" form and erode their cultural identity.
By the way, I'm a linguist (and a native Cantonese speaker) who is acutely aware of the dialect/language issues surrounding our topolect, so while I sympathise and thank you for recognising that Cantonese would in other times and places be considered a language, using "topolect" allows us to focus on the topic at hand.
It's a weak, flimsy word for people who know better, but still don't have the courage to say 'language'.
It's actually very similar to "topology" as a construction - "lexis" comes from "logos".
Some take this to be a bawdy anatomical pun, expressing the young man's hopes of 'standing' in his lady's 'grass' — a distinction lost nowadays that the pronunciation of "grace" and "grass" have grown so far apart.
(Line 88 of Chaucer's General Prologue, https://chaucer.fas.harvard.edu/pages/general-prologue-0)
There was an article that made HN a while ago about censor being spelled cesor in an inscription. Probably because /n/, like /m/, was serving to nasalize the vowel before and was not itself pronounced.
It also starts to hint at how the modern romance languages dropped all those case suffices. Eg. if bonus and bonum were both pronounced /bonu/.
I used to look at those topics and think in terms of what is "more like Latin", but at one point I realized... All of them are probably accurately capturing some form of the history of Latin, and there isn't right or wrong.
The article that mentioned cesor for censor also pointed out that in places where classical latin has -us or -um, early latin inscriptions might have -os, -om, or -o.
Sometimes i feel like when i hear speakers of modern romance languages talk really fast, unstressed o and u seem to get closer to one another. Maybe you could call it a continuum of "roughly that vowel".
And also, famously, "Babaorum".
Edit: oh, which btw does what you say, it's pronounced more with an "o" sound in French. Like all the "-um"'s. Otherwise "Petibonum" wouldn't work.

There was an excerpt somewhere where one Ancient Greek author (unfortunately I have forgotten who exactly) described the sound sheep were making, and he did so writing the following:
Sheep make the following sound: βαί, βαί
which could either be Bae, Bae, or Vae, Vae... (whereas nowadays we would probably use an 'm' to describe the sound, as in Mae mae) - so while the sound is described, it doesn't really provide a definite answer since both seem somewhat possible. But maybe the author of this article could help us out here!
Don’t think I have ever heard an initial 'v' sound though.
But if you look a little closer, it turns out that it can't conform to ordinary English spelling. There is no conventional way to spell a syllable-final /æ/, because the phonology of English doesn't permit such a syllable to exist at all. /æ/ is a checked vowel in English -- except for this one onomatopoetic word.
However your example is interesting because sheep make an "eee" sound like in "men" and not an "i" sound like in "flight", which I think is kind of how the erasmian pronunciation says it should be.
In modern Greek "αί" is one vowel sound "e" like in "men". I really don't like the erasmian pronunciation of ancient Greek - it seems strange that vowels should change so drastically across time when for example Spanish and modern Greek have exactly the same vowels.
Just look at English: the current ortography is so weird because it got frozen before the language underwent a drastic change (the Great Vowel shift).
German changed radically too: during the High German consonant shift, many of the differences that set it apart from English and Dutch happened: t got changed to s, p got changed to pf and so on.
Vowel shifts happened too: the Early New German diphtongization changed many long vowel sounds. For example:
* "latin" to "latein" (the "i" in Latin is like "ee" in English "see", the "ei" like English "eye"),
* "niuw" (almost like English "new") to "neu" ("eu" like "oy" in English "boy"), or
* "mus" to "maus" ("u" as "oo" in English "good", "maus" exactl% like the English word "mouse").
The last example is especially interesting because the Great Vowel shift and the Early New High German diphtongization started almost a continent apart and 800 years after the languages split, but had the same result.
My recollection is that Erasmus was the one who argued, based on that verse, that the letter eta should be pronounced as a long "e" rather than "i" as in "police". I can't seem to find a reference, however.
- S: sunus, L: sunus (son)
- S: avis, L: avis (sheep)
- S: padas, L: padas (foot)
- S: viras, L: vyras (man, also compare Latin vir [pronounced weer])
- S: dhumas, L: dumas (smoke)
- S: antaras, L: antras (other, second)
- S: vṛkas, L: vilkas (wolf)
- S: yuñje, L: jungiu (I join)
- S: jántis, L: gentys (tribes, also compare Latin gentes [a/the people])
- S: dantas, L: dantis (also compare Latin dentes)
- S: naktis, L: naktis (also compare Latin noctes)
I.e. a direct translation, word to word, works (with some style issues), but it's hard to recognize the sentence when pronounced.
This makes me wonder how sanscrit sounds...
Also, the language is quite complex, probably more complex than polish or russian, which is typical for archaic languages, afaik.
While it's very easy to pronounce Samskrta in a way similar to what was likely used in classical times, there have definitely been sound changes to an extent.
People are always going to speak how they want and eventually the 'correct' version isn't the majority. None of the many thousand people who have learnt Sanskrit in the eastern part of India would pronunce the name as 'Samskruta'. You could argue all day about how they are all wrong, that doesn't really change the fact.
Obvious example:
Arabic from at least the 7th century AD:
As an Arabic speaker, I can totally read a text the way it was pronounced 14 centuries ago and also perfectly understand it.
You cannot say the same thing for European languages.
Probably the same for sanskrit.
I may be able to do something similar in Spanish. I've read Emilianensian /Glosas/ in Navarrese-Aragonese and understand near the 95% of it. That being a close Romance to Castillian Spanish.
Scroll down and compare, you don't need to understand Spanish:
https://es.wikipedia.org/wiki/Glosas_Emilianenses
Also, I can perfectly read Don Quixote. My main issues would be the old Medieval slang with things that do not exist anymore or they changed a lot. But without the footer annotations, I had no issues at all to understand the 80% of it.
But, spelling it? Heck, it didn't change at all, our Spanish standards (Nebrija's grammar) date back to that era.
You probably cannot. Every region with a tradition of reciting the Qur'an has their own way of pronouncing it. It would be a strange coincidence if your tradition in particular happened to keep the pronunciation unchanged while all the others didn't.
E.g. do you pronounce ﺽ as a pharyngealized voiced alveolar lateral fricative? That's the most likely reconstruction of the sound: https://en.wikipedia.org/wiki/%E1%B8%8C%C4%81d
Exactly my point.
You’re under the impression I cannot because of your limited knowledge of this topic: even if 1 letter was slightly different (which it is not), how does that discard the prononciation of 99% of the rest?
>> Every region with a tradition of reciting the Qur'an has their own way of pronouncing it
Plain wrong.
If you knew the topic, you would know that the various way to read the Holy Quran are so close that you could just say they are identical.
In my original post, I’m not even necessarily talking about the holy Quran.
What about the vast poetry written in Arabic in pre-Islamic times that anyone today can read the same way?
I will not get into the subject of whether I would understand it or not since you are still debating whether I would pronounce it the same way.
BTW, this is very different from : how does one pronounce Latin etc.
Indeed, that is why modern scientists believe that ﺽ must have represented some kind of lateral sound, like a lateral fricative (or maybe a lateral affricate or a stop with lateral release – the descriptions aren't detailed enough to distinguish between these options.) But most modern speakers nonetheless pronounce it as a plain stop or dental fricative instead of lateral.
Having a description of the pronunciation doesn't mean that someone reading the description will be able to follow it perfectly. Otherwise everyone learning a foreign language would be able to develop a native-like accent just by reading about the correct pronunciation.
>The brahman was the reciter of hymns from the atharvaveda who was largely silent and observes the procedures and uses Atharvaveda mantras to 'heal' it when mistakes have been made.
As a Finnish speaker, "Ganges" has the familiar form of a name borrowed from Greek or Latin, and it does not need further adaptation. "Ganga", on the other hand, sounds awkward in Finnish. Had ancient Finns been in contact with India, we would probably know the river as Kanka or Kankajoki ("Kanka river"). The latter in particular sounds like a proper Finnish river name.
Place names are notoriously tricky. The town I live in is now called Yeovil. It has well over sixty documented spellings since around 500CE. It started off as Gifle - bend in the river. G -> Y is a common Old English/Saxon to modern English thing (-gard and -yard, -burg and -bury, dag or tag and day.) If you squint really hard you can get the rest of the word OK. It was Ival, Givelle, Evil and all sorts of spellings on the way to today. There was also a vowel shift en-route and a generally open approach to spelling.
In Greek we have adopted many Turkish words and we always stick an "-i" at the end. For example, "passoumi" (a kind of footwear, "passoum" in Turkish), "briki" (for making coffee, "brik" in Turkish), "ati" (horse, "at" in Turkish) etc. I think we've also taken some Slavic words and treated them this way, for example "boureki" (borek, dumpling), kokoretsi ("kokorec") and probably others I can't think of now.
There is strong evidence that the ळ came from Substratum languages (Dravidian or Munda) and many Indo-Aryan languages still retain it e.g. Marathi, Gujarati.
I also think this is so because the prevalent narrative is post colonial in nature and the (English) Internet is came out of Anglosphere. This is not a criticism of the prevalent order, it's just the way things have evolved naturally post WW2.
Ancient Sanskrit pronunciation was essentially similar to what we call the Prakrit language, which was a more colloquial version and spoken by most people. Bengali, Marathi and Gujarati are a bit closer to that pronunciation, but of course they have changed a fair bit too.
This has to be the most far-fetched and absurd claim I’ve heard so far. Sanskrit has been orally transmitted since several millennia and there’s no change in its pronunciation and grammar since days of Panini. That robust oral tradition is well researched and proven to be fool proof.
Likewise, we have older information on pronunciation as well in the Pratishakhyas.
Ancient Indians cared a lot about accurate pronunciation, especially for mantras where the thinking was that without correct pronunciation, the mantra would not work. Picture the Harry Potter "wingardium leviosa" scene.
Modern don’t actually hew to the prescribed pronunciation for certain letters, but it’s certainly specified by Panini.
Your kind of hot take about Sanskrit is somewhat common.
Relatedly, I went to a spoken Latin event where I (an American) spoke Latin with an Italian man. His pronunciation and mine were wildly different, although we could understand each other. Neither was all that similar to the academic linguists' view of what our conversation would have sounded like thousands of years ago, though I guess his vowels were generally closer and my consonants were generally closer.
People retaining ancient languages for liturgical and scholarly uses are generally not that great at preventing the pronunciation from shifting, and I think that's true across the board. ("Atque memento, nulli adsunt Romanorum qui locutionem tuam corrigant." -- Henry Beard.)
https://en.wikipedia.org/wiki/Shiva_Sutras#Arrangement
So while a present-day understanding of classical Sanskrit grammar could be derived fairly directly from his work, that's still not any guarantee that you would pronounce Sanskrit just as Panini would have.
A moderately imperfect analogy is that while Jews have been carefully learning to read, recite, and copy the Torah for thousands of years -- including reading commentaries, which, while nowhere near as systematic or thorough as Panini, elucidate lots of grammatical issues -- there still emerged huge, systematic regional differences in the pronunciation of particular Hebrew letters, even in liturgical use.
https://en.wikipedia.org/wiki/Ashkenazi_Hebrew
https://en.wikipedia.org/wiki/Sephardi_Hebrew
https://en.wikipedia.org/wiki/Mizrahi_Hebrew
https://en.wikipedia.org/wiki/Tiberian_Hebrew
among several others. The people using each pronunciation were often incredibly sophisticated in their religious scholarship and incredibly familiar with the underlying material, but they definitely didn't (and don't) pronounce it the same way.
Modern linguistics has been able to find evidence for comparing these pronunciation variants and also understanding their histories, and I believe something similar is true for Sanskrit pronunciation.
No, that’s not true. there’s a bunch of varieties of Sanskrit, including Vedic Sanskrit, Classical Sanskrit, and various local dialects. Not all of these have been preserved in oral traditions.
Second, even within the preserved oral traditions, pronunciations vary across schools. For example, the “kru” part in your Samskruta is pronounced differently in different parts of India; some people do say “kri”
Leaving aside the linguistic debate in the comments here, there’s often no fair or truthful or representative discussion of the ancient East’s legacy (or others) for reasons relating to imperialism, colonialism, and supremacist thinking. I don’t mean that in the explicit “we’re taking over your country way” but in the more subtle or implicit ways. Western world views and Eurocentric histories are everywhere, from academia to Wikipedia, and due credit or consideration isn’t given elsewhere.
The problem persists even in the very countries we are talking about, like India, since their earlier “original” Hindu culture was changed by invasions (whether from the Islamic Middle East or Christian Europe). My understanding is that when the British finally left India, their academic culture still persisted in the form of Western education that replaced earlier forms of education, textbooks sourced from Western publishers, taxpayer funding into this system, and the adoption of languages like Hindi and English as the official languages (rather than say Sanskrit or Tamil).
So to answer your question in the broader sense beyond this article and discussion, there is no discussion of these things in part because of the power of Western spheres and in part because Eastern spheres themselves haven’t retained their own knowledge or promoted themselves adequately either domestically or internationally.
Lots of the original way people thought, lived their culture and worshipped in their religion has changed.
And your quibbling is indicative that there have been also been changes today as well - e.g. southern speakers tend to pronounce vowel r as “ru” while others say “ri” and at some point in time the pronunciation was likely more like American English r.
And regular people didn't speak sanskrit in classical age. They spoke regional languages like Prakrit and Pali.
But I don't like how it sounds in the video, and those weird sound bits (no idea what you call them) is not very friendly for singing either.
Could you describe in more detail which bits sound weird? Of course Old Chinese would sound very different to Mandarin, but I didn’t notice anything actually weird about it.
From what I understand Rosetta Stone simply provided a dictionary of sorts, so I can understand how they know which words mean what. But how do they know that a certain combination of hieroglyphs translates into words pronounced as say “Ramses” or “Tutankhamen “ and so on.
I found this to be a great source on the topic. Your question is a great one, and hints as to why Jean-Francois Champollion is hailed as the genius he was. The key insight was essentially the theory that the Coptic language spoken still as the liturgical language of Coptic Christians in Egypt was a modern form of the ancient Egyptian language encoded by Hieroglyphics. Champollion made a key insight attempting to decipher a cartouche (the hieroglyphic form used to write a name) that a symbol at the beginning of a name looked extremely similar to a sun. The Coptic word for sun was Ra. At the time, they’d already identified the symbol used to writes a ‘ss’ sound, and so Champollion was able to guess at the middle symbols spelling Mes, leading to the deciphering of Rameses. Note that the European world at large obviously already knew the name Rameses, which was key here.
I believe in general names were key to deciphering many of the sounds used in the language, coupled with pronunciations hinted at by Coptic.
I typed this all by memory so I may be off in some details but I believe I have the gist right.
However, these pronunciations are full of issues and uncertainties - in part because, as the OP states, even figuring out how exactly Greek was pronounced is sort of a challenge, and because Ancient Egyptian did not denote most vowels, so some uncertainty is unavoidable.
For example, Egyptologists will usually transcribe the name we usually pronounce as Tutankhamen as "twt-ꜥnḫ-jmn". We can tell which phonemes are distinct and have some idea of how they must have been pronounced, but we can never truly know for sure.
So the answer is: The word probably wasn't pronounced as "Ramses", the name "Ramses" is an approximation of a Greek approximation of the actual name of the pharaoh, optimized to be easy to pronounce by English-speakers.
So basically it seems they used the proper nouns to start and then built up on that. And also used Coptic to fill gaps..
I do get the point about Greek approximation since just as an example in modern India, Alexander is referred to as Sikander. Similar, yet very different.
https://en.wiktionary.org/wiki/%E1%BC%80%CE%BB%CE%AD%CE%BE%C...
I think the a- in the al- in Alexander is supposed to be the alpha privative
https://en.wikipedia.org/wiki/Alpha_privative
like our "ward off" or something.
Also, wikipedia says this about alpha privative:
>> It is derived from a Proto-Indo-European syllabic nasal n̥-, the zero ablaut grade of the negation ne, i.e. /n/ used as a vowel.
But the wiktionary article says this about αλέξω:
From Proto-Hellenic aléksō (“to protect”), from Proto-Indo-European h₂lek- (“to defend”) (...)
Note the difference between "n̥" and "h₂". I don't even know what those are, but they seem different enough that they may be ... different?
In the case of Ramses specifically, there is also a piece of biblical evidence, the city recorded in Hebrew as something like "Raamses". https://en.wikipedia.org/wiki/Pi-Ramesses#Biblical_Ramesses
The two biblical cities of Pithom and Raamses are traditionally identified as the Egyptian "per-Atum" and "per-Ramesses", for some convention on spelling the Egyptian names.
I was interested to learn that the name of Ra is attested in these letters! From that, we know the vowel -- it was /i/.
(The "a" in Ra is a consonant which is traditionally rendered as "a" by convention.)
Ancient Egyptian was related to other languages, and was part of the rather large still-existing Afroasiatic language family, which includes Semitic (Hebrew and Arabic and others), Berber (of north Africa), and many others. (Importantly, Akkadian is one of the first written languages aside from Ancient Egyptian itself, and it was a very early Semitic language, and not so dissimilar from Ancient Egyptian in some ways.)
While only reconstructions, this gives us, in a sense, a model of the ancestral language of Ancient Egyptian. This insight provides more data on possible phonetic values and the nature of that language. There is always a great deal of uncertainty though.
By comparison, Sumerian, of similar antiquity, was an isolate and we do not know any language related to it. We have many texts in Sumerian, and many parallel texts between Sumerian and Akkadian, as well as old Indo-European languages like early Persian. We kind of have the sketch of its sounds. But even then, we have less idea what Sumerian sounded like, or how its grammar works, or what its words mean, than we do Ancient Egyptian. And that is despite the fact that Ancient Egyptians didn't write their vowels while the Sumerians did! Having related languages you can compare to is valuable here.
'CAESAR' sounds positively German and Legio VI Victrix has an effeminate sound. I'm afraid that Biggus Dickus had at least a little to do with attitudes towards proper Latin.
The difficult task of reproducing the pitch accents in Greek might be a step too far for most people, but consider the following line from Homer’s Iliad 1.345:
ὣς φάτο Πάτροκλος δὲ φίλῳ ἐπεπείθεθ᾽ ἑταίρῳ
It develops beautifully from sauntering labial alliteration (of p and ph sounds) to rapid-fire dental consonance (of th and t sounds), but if we pronounce Φ and Θ as fricatives here:
https://antigonejournal.com/wp-content/uploads/2021/07/Iliad...
rather than aspirated stops:
https://antigonejournal.com/wp-content/uploads/2021/07/Iliad...
then the distinction between Φ and Π and between Θ and Τ becomes so great that the sound effect is lost completely. Homer, for one, would have cared.
That's the Erasmain pronounciation, if I remember correctly: saying vowel dipthongs as two separate vowels. That really sounds awful and very much not like Greek.
