offender

The word 'offender' is built upon the verb 'offend', which entered English from Old French offendre, itself derived from Latin offendere meaning 'to strike against' or 'to stumble upon'. The Latin term is a compound of ob- (against) and -fendere (to strike). The agent suffix -er, of Germanic origin, was added to create a noun specifying 'one who offends'. Thus, the literal sense of 'one who strikes against' evolved through legal and social contexts to denote someone who violates a law or a social norm, shifting from a physical to a primarily abstract or legal confrontation.

Structure: offend + er offend: From Latin offendere (to strike against, displease). Functional role: verbal root. er: From Old English -ere, an agent noun suffix. Functional role: suffix denoting a person who performs the action of the verb.
