Actually languages aren’t made from random mouth sounds, only a small portion of the wide range of possible sounds is used for language. The International Phonetic Alphabet can notate all the phonemes (individual sounds) of all human languages and does so with only I think 107 letters and around 50 diacritics (and a handful of other marks). English uses around 44 phonemes (a phoneme being an individual sound). There’s a language in the Pacific somewhere that uses only 11 phonemes. How I do not know. And there’s a click language in southern Africa that has I think 112. You could do amazing things with 112 phonemes.
There was a language in Turkey that had only two vowels and eighty some consonants. It is extinct now, killed off in the greatest consonant clusterfuck of all time. That’s a linguistics joke.
I know a funnier one about a lady in Boston who asked a cabbie if he knew a place where a woman could could get scrod.
