the word 'theatergoer' is a transparent english compound formed from three native and borrowed elements. the first part, 'theater', has a long lineage from the greek 'theatron', meaning 'a place for viewing', which entered english via latin and french. it is combined with the old english verb 'go', meaning to move or travel, and the agent suffix '-er', also from old english, which denotes a person who performs an action. the compound's logic is perfectly literal, describing 'one who goes to the theater'. this modern formation follows a classic germanic pattern of verb+agent construction, applied to a culturally specific activity centered on a classical institution.
