Don’t get me wrong, i think linguistics is a lot of fun and i get that it’s an interesting field. I just don’t understand what practical applications it has beyond understanding languages better. What do we do with that understanding of languages? Is it purely about seeking knowledge?
Maybe you want to re-read the question? They’re asking about the practical use of linguistics, and this answer combined with your other one is basically “language is very practical so duh, we should study it”.
But what do you do with the results of those studies? That’s what the question is about.
