Trying to read Farsi, it feels like I should know what's going on but am left with the feeling that I've forgotten all my Arabic. Then I'll see some of the bonus letters.
Wait till you discover Urdu, which confuses Farsi speakers even more. For extra fun try the Nastaliq script.
This is what Dutch sounds like to me as an English speaker - plenty of common sounds with English; it has a similar speed, rhythm, intonation to English. It feels like I’m hearing English but have lost my faculties to parse it
"Goedemorgen, ik hoop dat je bent goed".
He was in the war -- Hij was in de war (he was confused)
A stiff in the brook -- Een stijve in de broek (a boner in the pants)
Those are the two most famous examples I'm familiar with, but I'm sure there are a lot more.
One of her friends was half of a multi-nationality couple, I think it was French and Irish, and the punchline was their kid, at a beach, yelling, in a strong Irish accent "Look mummy! Phoques!"
It was certainly something close to what I wrote.
Also I wonder if there's a connection between trousers being "broek" in Dutch and "breeks" in Scots.
edit: wow ok I should've just went to wikipedia: https://en.wikipedia.org/wiki/Breeks
"Jah" "Oui" "Sí" "Ja" "Da"
Portuguese and Italian on the other hand are much closer, and if spoken slowly enough, somewhat understandable.
If you live in Europe and speak a language using a Latin script, you probably have come across most of the extensions other European languages add to the shared base in loanwords or foreign media. But then you look at something like Vietnamese and you are no longer sure how letters work.
Looking back on it, I remember feeling like I can't remember Arabic, but part of it is that this also happens during that time when I'm getting used to the script. There is always an adjustment period with every new font/handwriting that takes a sentence or two to sort out the style before I truly start reading.
3. The text is in the wrong Arabic-script language, for example Farsi in Egypt (Egyptians primarily speak an Egyptian Dialect of Arabic), or Modern Standard Arabic in Afghanistan (Afghans speak Dari, an Afghan Persian language). Comme l'alphabet latin, vous pouvez écrire différentes langues avec l'alphabet arabe.
Syriac script looks completely different to Arabic but has the same issues when rendered
But note that in some cases, eg https://en.wikipedia.org/wiki/Tajik_alphabet#Samples point number 2 won't be accurate. I'm not the best reader of Tajik written in (Perso-)Arabic script, but I don't believe "ال" appears in the samples there. (It does appear in the word "ALphabet" in the opening paragraph!)
