Interesting thoughts on the dilution of language.
it's very interesting. It can go either way as well. English is becoming easier and easier. look at Black English (as linguist refer to it). It is a form of English that evolved out of adult (over the age of 3) African "immigrants" (slaves, actually. but they were not born in English), trying to learn the English language. they did the best anyone above the age of 3 could do. especially since education was mostly denied to them. Black English does have its own grammar. it isn't really a "stupid" English. Just a different one. It may sound annoying to the well-educated that a person say "I be going to the store"... but if you think about it, conjugating the verb "to be" isn't really all that necessary. Our educated English is wrong from a century ago. which was wrong to a century before it. and so forth.
adults learning English as a second language, learning in incompletely, and for some reason become the majority speakers so that their version takes over. that plus the natural evolution of language.
The natural evolution of a language. Where simplification can actually make the language more difficult. One such example is where consonants get softer till they drop off into oblivion. this can be nothing in English. But in one of the Chinese languages(I think), there are words where, to the untrained ear, the same sound means 3 completely different words. the trained ear notices that there is a difference and it is the inflection of the vowel. kind of hard to describe in writing. but you can figure it out once I explain how such a complicated thing evolved.
take the sound i as in it. i can mean 3 things depending on the inflection. what linguist believe is that the way this evolved is that at one time, it wasn't the vowel i, it was 3 individual words. like it, is, and ill. notice that while the i sound is the same, there is a different kind of inflection on the sound in each word. so if you drop the t, the s, and ll. you have just the same i, but three different kinds of i.
It's crazy! and absolutely fascinating!
