'armigeral' originates from Latin through formation with the adjective suffix '-al', ultimately based on the Latin noun 'armiger' meaning 'arms-bearer' (from 'arma' 'arms' + 'gerere' 'to bear').

The Latin noun 'armiger' ('arms-bearer') entered Medieval/Old French and Middle English as 'armiger', and the adjective form was later formed in Modern English by adding the suffix '-al' to produce 'armigeral'.

Initially related to a person who bore arms ('arms-bearer'), the term as an adjective came to mean 'relating to or bearing a coat of arms' or 'heraldic' in modern usage.
