>English is not "sloppy", not any more than any other language.
Yes it is, and you say so yourself:
>Unfortunately its spelling was standardized just before it underwent a huge change in pronunciation, and its habit of borrowing words from other languages without changing their spelling, has left it with fairly chaotic orthography.
>A few phonetic features - unusual consonants like th, difficult to learn rules around stressed syllables, nasty consonant clusters (squirrel!) - do make it tricker than it could be for second language learners.
Most other languages don't borrow words so profligately, and have much more regular relationships between their written form and their pronunciation.
>but many features of modern English are the result of so many people learning and speaking it.
Right, and that makes the language "sloppy", which was my point before. You can't have a language shared by so many different people and cultures as a common trade
language and have it stay as orderly and precise as German, for example.
>But the grammar is generally not too difficult - no grammatical gender, no case aside from a few pronouns, outside of a handful of irregular verbs conjugations are pretty easy
Yes, and these features all make the language much easier for people to adopt as an international language, despite the sloppiness. I have a hard time imagining Russian or German having had this success in a parallel universe. As an example, look at Dutch: the Netherlands is another country that got rich from trade, and was also a colonial power. But who outside of the Netherlands speaks Dutch? South Africa is the only place the language actually went anywhere. Meanwhile, the former colonies of Spain all still use Spanish.
