the word "unquestioning" is a modern english formation built upon the well-established verb "question," which entered english from old french 'question,' itself derived from latin 'quaestio' (an inquiry, investigation), from the verb 'quaerere' (to seek, ask). the negative prefix "un-," of old english origin, is systematically attached to adjectives and participles to denote the opposite quality. the suffix "-ing," also from old english, is commonly used to form adjectives indicating a characteristic or action. therefore, the literal construction "not + asking + (adjective marker)" logically yields the modern sense of accepting something without inquiry or doubt, perfectly illustrating the transparent and combinatorial nature of english word formation.

Structure: un (not) + question (ask) + ing (adjective suffix) - un: a prefix of germanic origin (old english) meaning "not". - question: a noun/verb from latin via old french, from 'quaestion-' meaning 'a seeking, inquiry'. - ing: a suffix of germanic origin (old english) used to form adjectives from verbs or nouns, meaning "having the quality of".
