Why does language change?

Answer 1

What I've found is that language changes for many reasons:

a) The people, over time, added vocabulary to the current language as advances were made in science, technology and industry, and applied the new words and forms of the new words to everyday life.

b) Different peoples influenced the other's language, whether through peacetime and trading, or war and parley negotiations.

c) Various words are forgotten or became obsolete, which was usually accompanied by rapid changes or advances in society (such as when one part of the world conquers another part of the world).

d) Sometimes a language becomes influencial in a culture following colonization, as in The US and in India for example. English became the dominant (until now) language in the US, and a major language in India. The Englishes spoken in both places become modified to fit the needs, customs and useage of the inhabitants. The three Englishes here, British, US and Indian, are a little different from one another in pronunciation, vocabulary, spelling and useage.
