Quibble

(n.) A slight objection or criticism about a trivial matter; (v.) argue or raise objections about a trivial matter.

Origin uncertain. Possibly from quib (“quibble”, noun) +‎ -le (diminutive ending). Quib is probably from Latin quibus (“in what respect? how?”), which appeared frequently in legal documents and came to be suggestive of the verbosity and petty argumentation found therein; or perhaps an alteration of quip. Alternatively, perhaps related to dialectal Dutch kwebbelen (“to speak quickly and continuously, chatter”). Compare also Scots wheebele (“a quibble”).
