quibble

Quibble can also be a noun meaning "an evasion of or shift from the point" or "a minor objection or criticism." Both forms of the word arrived in English in the mid-17th century. Presumably (though not certainly) quibble originated as a diminutive of a now obsolete word, quib, which also meant "quibble." In fact, although language experts may quibble over this, there is a possibility that quib can be traced back to the plural of the Latin word qui, meaning "who," which was often used in legal documents. If so, that makes quibble a very distant cousin of the English word who.
