pork: [13] Latin porcus ‘pig’ went back to a prehistoric Indo-European *porko-, which also produced Russian porosenok ‘pig’, Irish orc ‘pig’, and English farrow. It passed into Old French as porc, which English adopted as a term for the ‘flesh of pigs used as food’. Derivatives that have made it to English include porcelain, porcupine, and porpoise. => farrow, porcelain, porcupine, porpoise
