puzzling

the word 'puzzling' is built upon the verb 'puzzle', whose own origins are somewhat enigmatic, first appearing in the late 16th century. it may derive from a frequentative form of an obsolete verb, implying a repeated action that causes bewilderment. the addition of the present participle suffix '-ing' transforms the action of causing confusion into an adjective describing something that possesses that very quality. thus, the literal construction "causing to puzzle" evolved seamlessly into the modern abstract meaning of being confusing or difficult to comprehend.
