questioner

The word 'questioner' is a transparent agent noun formation built upon the noun 'question'. The core noun 'question' itself originates from Latin quaestio, derived from the verb quaerere meaning 'to seek, ask'. This verb is traced further back to the Proto-Indo-European root kʷeh₂-, which carried the sense of 'to acquire, gain'. The semantic journey thus evolved from the broad concept of 'seeking to acquire' to the more specific act of 'seeking information through inquiry'. The agent suffix '-er', of Germanic origin, was productively appended in English to create a term for one who performs this specific action of asking.

Structure: question (to ask) + er (one who does) - question: From Latin quaestion- (stem of quaestio), meaning 'a seeking, inquiry, question'. Its functional role is the core semantic base. - er: From Old English -ere, an agent noun suffix indicating 'a person or thing that performs an action'. Its functional role is to form a noun denoting the agent of the verb.
