Etymology

Attested in English since 1530, from Latin prōtēctus (“covered, protected”), past participle of prōtegere (“to cover the front, protect”) from prō, prō- (“before, in front of”) + tegere (“to cover”), see tegument. Displaced native Middle English shelden, from Old English sċildan (“to protect,” literally “to shield”).
