New words are still real words

I didn’t claim they weren’t. Anyone can coin words, but whether they “become real” or not is just up to whether anyone else stars using them and or if they’re made up of already known components which clearly indicate the meaning. Like for instance if I wrote random gibberish that I myself had assigned meaning to, you wouldn’t be able to tell what it meant unless I used already existing words / conventions for coining new words.

That’s the private language argument.

Obviously there are loads of words which get coined and instantly spread in usage, so the “age” of a word doesn’t have meaning. The word having meaning is what matters.

If I wrote down lsdkbrjfufurbrnfnflslejje, is that a “real” word? Obviously it’s just gibberish I wrote down, but what if I say it means a very specific thing. Does that then make it real? If people started using it, sure.

You very well know what people here mean by “real”.
