Etymology

The word pear is probably from Germanic pera as a loanword of Vulgar Latin pira, the plural of pirum, akin to Greek apios (from Mycenaean ápisos), of Semitic origin (pirâ), meaning "fruit". The adjective pyriform or piriform means pear-shaped. The classical Latin word for a pear tree is pirus; pyrus is an alternate form of this word sometimes used in medieval Latin.
