Origin & History of “pig”

The word pig is not recorded until the middle English period, although it is assumed to have existed in Old English as *picga or *pigga. It originally meant ‘young pig’, and did not become the general term for ‘pig’ until the 16th century (the usual word in Old and Middle English was swine). Piglet is a late 19th-century coinage. It is not known where the word pig came from, although some have suggested a connection with Old English pīc ‘pointed object’ (source of modern English pike), perhaps in allusion to the pig’s pointed muzzle (if that is the truth of the matter, pig may be parallel as an animal-name with pike).
