Word Origin & Etymology

The drainage sense derives from Middle English sewere, from Anglo-Norman sever, ultimately traced to Vulgar Latin exaquaria ("channel for draining water out"), from Latin ex- ("out") and aqua ("water"). The garment-making sense derives from Old English siwian ("to stitch") plus the agentive suffix -er.
