yea but most of those are slang...then the fact that they are different in other language due to the gender/tense/etc...not just synonyms.
Like you use yes , yeah, yep in the same place. In spanish, etc you use the different forms in special spots. That's what I'm talking about. I know all language has synonyms lol..but others you HAVE to use the other form in order to sound right.
It's like only being able to say "yes" with certain words while only being able to use "aye" with certain others....
