Language is always evolving, never static. A dictionary and the definitions are backwards looking always. Dictionaries are always trying to keep up with the evolutions of language, but they’ll always lag behind.

Just keep in mind that words change how they’re used over our lifetimes, and it never stops.

E. G. Irregardless is now a valid word, when 15 and 20 years ago it was people mixing up regardless or irrespective so now I don’t even get that high horse anymore 😉
