a shortened form of the word "legitimate". however, this term is nowhere near the real meaning of "legitimate", since it is commonly used to describe things as cool or extremely awesome.

Short for "legitimate". NOT short for "legitimately" which is a totally different word. The difference is roughly the same as between "good" and "well" – in case you cared. An extremely popular yet badly understood filler word.

Sparky: "IKR? He could've been literally one of the greatest, though."

1. (adj.) A modern synonym for words such as "cool," "ill," "tight," or "dope." Used to describe a noun that is of a particularly excellent quality. The slang use of this term is slowly but steadily increasing in popularity.

2. (adj.) Authentic. see legitimate.

this word was obviously a short form of "legitimate" but it no longer holds the same meaning as legitimate, since it has become very popular to use the word legit to mean something "cool", which really has nothing to do with the word legitimate and therefore we should stop saying it.
"Wow Kelly's shoes are legit"
