Middle English pere, from Old English pere, peru "fruit of the pear tree," common West Germanic (Middle Dutch, Middle Low German pere, Old High German pira, bira, Dutch peer), from Vulgar Latin *pera, variant of Latin pira, plural (taken for fem. singular) of pirum "pear," a loan word from an unknown source, perhaps Semitic or a lost Mediterranean language. It likely shares an origin with Greek apion "pear," apios "pear tree." Their cultivation began as much as 3,000 years ago.
