retainer (English)

Where does "retainer" come from?

The English noun 'retainer' is formed from the verb 'retain' combined with the agent suffix '-er'[1]. The verb 'retain' entered Late Middle English from Anglo-Norman 'reteiner', Middle French 'retenir', and Old French 'retenir', which meant 'to keep back, retain' or 'to engage in one's service'[2]. These forms trace back to Vulgar Latin '*retinīre' and Latin 'retinēre', meaning 'to keep or hold back'[2], composed of the prefix 're-' meaning 'again' and the verb 'tenēō' meaning 'to grasp, hold'[2]. Ultimately, 'tenēō' derives from the Proto-Indo-European root '*ten-' meaning 'to extend, stretch'[2].
