I was writing an email to a colleague this morning and I used the verb "jibe." I don’t believe I've ever actually written the word before in my life and I was compelled to look it up out of curiosity. I was using the word in the American English meaning of "to agree with" in my email.

jibe, v.
Chiefly U.S.
intr. To chime in (with); to be in harmony or accord; to agree.
gibe, jibe, v.
1. intr. To speak sneeringly; to utter taunts; to jeer, flout, scoff. Const. at,  with. Also dial. to scold.
2.  trans. To address with scoffs and sneers; to flout, taunt.
