conundrum: [16] Conundrum originally appeared in all manner of weird and wonderful guises – conimbrum, conuncrum, quonundrum, connunder, etc – before settling down to conundrum in the late 18th century. It bears all the marks of one of the rather heavy-handed quasi-Latin joke words beloved of scholars in the 16th and 17th centuries, and a mid-17thcentury commentator attributed it to Oxford university. At first it meant ‘whim’ and then ‘pun’; the current sense ‘puzzling problem’ did not develop until the end of the 18th century.
