Yes, and so is every other human language! Language is always changing, evolving, and adapting to the needs of its users. This isn’t a bad thing; if English hadn’t changed since, say, 1950, we wouldn’t have words to refer to modems, fax machines, or cable TV. As long as the needs of language users continue to change, so will the language. The change is so slow that from year to year we hardly notice it, except to grumble every so often about the ‘poor English’ being used by the younger generation

Why does language change?

Language changes for several reasons. First, it changes because the needs of its speakers change. New technologies, new products, and new experiences require new words to refer to them clearly and efficiently. Consider texting: originally it was called text messaging, because it allowed one person to send another text rather than voice messages by phone. Another reason for change is that no two people have had exactly the same language experience. We all know a slightly different set of words and constructions, depending on our age, job, education level, region of the country, and so on. We pick up new words and phrases from all the different people we talk with, and these combine to make something new and unlike any other person’s particular way of speaking. At the same time, various groups in society use language as a way of marking their group identity; showing who is and isn’t a member of the group

Language will never stop changing; it will continue to respond to the needs of the people who use it. So the next time you hear a new phrase that grates on your ears, remember that like everything else in nature, the English language is a work in progress.
