repairer

the word 'repairer' is a straightforward agent noun formation in english. its core, 'repair', originates from the latin verb reparare, a compound of re- ('again') and parare ('to make ready, prepare'). this literal sense of 'restoring to a state of readiness' evolved into the general modern meaning of fixing or mending something broken. the agentive suffix '-er', of germanic origin and common in old english, is then appended to denote a person or thing that performs the action of the verb, resulting in the transparent meaning 'one who repairs'.

Structure: repair + er repair (from latin reparare, meaning 'to make ready again', functional role: verbal root) + er (from old english -ere, a suffix forming agent nouns, functional role: agentive suffix)
