the word is a modern english formation built upon the core noun and verb "question," which entered english via old french from latin quaestionem, a derivative of quaerere meaning "to seek, ask." the negative prefix "un-," of old english origin, is attached to create the meaning "not questioning." the adverbial suffix "-ingly" is a productive combination in english, where "-ing" creates a participial adjective and "-ly" converts it into an adverb. thus, the literal morphemic sequence "not" + "asking" + "in the manner of" logically constructs the modern sense of doing something in a manner devoid of doubt or inquiry.

Structure: un (not) + question (ask) + ingly (adverb suffix) - un: a prefix of germanic origin (old english) meaning "not," used to form negatives. - question: a noun/verb of latin origin (from latin quaestio, quaerere 'to seek, ask'), functioning as the core lexical root. - ingly: a compound suffix consisting of '-ing' (forming a present participle or gerund) and '-ly' (forming adverbs), both of germanic origin (old english).
