Pronounced: in-tuhr-PEH-late, verb
Notes: It sounds a bit like interpolate, but interpolate is a different word.
The word divaricate means, as a verb, “to branch off or diverge”. The adjective means “branched off or diverging widely”.
Like many of the words I post, this word also comes from Latin. This time, it is from divaricare, which is composed of dis- (apart) and varicare (to straddle).
The word goes back to the early 1600s
