## AI Etymology
Unquestionable comes from un- ('not') + questionable, from question, from Old French question, from Latin quaestio ('a seeking, inquiry'), from quaerere ('to seek, ask'). The historical chain includes Old English un- and Latin quaerere. The quoted older senses, "not", "a seeking, inquiry", and "to seek, ask", supply the semantic anchors for unquestionable. The formation is best read as compound and borrowed: the word unquestionable carries its older form-history into a compact English lexical shape. In present English it is used as a adj, "not able to be disputed or doubted; certain". English derivatives include unquestionably and unquestionableness; related English forms include question, questionable, and unquestioned. The result is a adj whose etymology preserves both the older form and the later English specialization.
