I thought I should point out the other side of the argument. As a languages student (which doesn’t just mean learning foreign languages but also studying the development of language itself), I need to point out to you all that language is fluid and changes over time. Not just lexically but also gramatically. How do you decide what is right? Originally, in many countries it was based on the most widely used forms among the dominating social groups. If we were to hang onto the original forms and meanings, language would be very different to how it is today. Have you thought that maybe literally no longer just means what you say it means, but has recently taken on new meaning? That is how language develops!
This wasn’t intended to rubbish what you say, but there is a difference between using language badly, and using it in a way that does make sense. I’ve posted this to Statto too.
