Acronyms are abbreviations using only the first letters of each word in a phrase. That way, you can use an expression more quickly.

They are very used in written language, so check out the meaning of these acronyms.

Idk → I don’t know
LOL → Laughing out loud
Hbu → How ‘bout u (how about you)
Btw → By the way
