Umm... No there are at least 5999 other languages on Earth.
For the last time, I'm not learning a language.
Wow! You must know many languages then!!
Okay, so there's a difference between 'learn' and 'study'. Well, I do the latter.
I have done Linguistics in my Literature course.
Yes, we get that A LOT.
I hope now you feel like opening a new tab and actually finding out what Linguistics is all about. :)
