A boar is a powerful male swine, bred on farms for reproduction or encountered in its wild form as a formidable animal. Its tusks, strength, and unpredictable temper give it a more forceful literary presence than the ordinary farm pig. In poetry, the boar may symbolise virility, aggression, appetite, courage, or destructive energy. When placed in a farm setting, it can evoke breeding, confinement, and animal husbandry; in mythic or pastoral verse, it may bring danger into cultivated land.

A boar is an adult male pig and carries stronger associations of power and aggression than the general word pig. On a farm it may represent breeding stock, animal strength, appetite, or dangerous instinct held within fences. In mythic or narrative poetry, a wild boar often brings violence and chaos into cultivated or civilised space. Students should determine whether the animal is domestic or wild. Related terms include swine, sow, piglet, sty, tusk, rooting, livestock, and husbandry.
