I googled male pig word and got results that said the word was boar. I thought, "That's odd; I thought that was the word for a wild pig!" So I visited Dictionary.com and sure enough, it has both meanings:

boar [bawr, bohr]
1. the uncastrated male swine.
2. wild boar.
3. South Midland and Southern U.S. (of animals) male, especially full-grown: a boar cat.

So I was wondering, since there exists a term that only means female pig--sow, does such a word exist that only means male pig and nothing else? I'm looking for a unique term.

    There is hardly any word at all that means only one thing.... – Hellion Mar 23 '14 at 3:31
  • @Hellion Considering that there are numerous distinct words for cattle, it's a pretty reasonable question. – David Pope Mar 23 '14 at 3:37

    Boar is a perfectly acceptable term for a male domestic swine. That's why wild boar is always termed wild. Otherwise, it would just say boar. – David M Mar 23 '14 at 3:39

    Fun fact: a sow can also be a female of several other land mammal species, including bears and badgers. – user2310967less Mar 23 '14 at 8:29

    Are there also "wild sows"? There must be; I assume not all wild boars are escapees from captivity. – GEdgar Mar 23 '14 at 13:19

There are three terms used for this purpose. Here's a description of all three from Wikipedia.

  1. Boar or hog, male pig of breeding age.
  2. Barrow, male pig castrated before puberty.
  3. Stag, male pig castrated later in life (an older boar after castration).

  • So there's no term that can't be confused with wild boar? That's disappointing! – Brian J. Fink Mar 23 '14 at 3:42

    @BrianJ.Fink Context matters. And in most case it's context that clears up the confusion. – Noah Mar 23 '14 at 4:03
  • A note on "stag", since it's not the common usage of the word: When used in this context, it means any animal that was castrated after reaching sexual maturity, or cattle or sheep castrated before sexual maturity. – Izkata Mar 23 '14 at 4:41

If the species is called "hog" (AmE), the name for a full grown male hog is "boar", and "pig" for a young, weaned hog or any immature hog, and a "piglet" for a little pig, especially a suckling one.


If the species is called "pig" (chiefly BE) or "swine", the name for a mature male pig is "hog", "shoat/shote" for a young, weaned pig or any immature pig, and "piglet" for a young, unweaned pig.

    Not to be confused with hogg, hug or ugg which colloquially means sheep in parts of Scotland and Cornwall. – cup Mar 23 '14 at 10:00

    Your answer gives several specialized names unique to various stages of development. Perhaps I should clarify that I seek a unique term for the adult male pig, and it pains me that its name is so easily confused with a wild swine, regardless of gender. – Brian J. Fink Mar 23 '14 at 19:43
  • @BrianJ.Fink The thing is a wild boar can also be referred to as a wild hog or a wild pig m.myfwc.com/wildlifehabitats/profiles/mammals/land/wild-hog – Elian Mar 23 '14 at 20:08
  • I only care about the ambiguity of the word boar. – Brian J. Fink Mar 24 '14 at 0:50
