Definition:

  • (n.)

It was formerly supposed to be a subtile, imponderable fluid, to which was given the name caloric.

  • (n.) Utmost violence; rage; vehemence; as, the heat of battle or party.
  • (n.) Agitation of mind; inflammation or excitement; exasperation.
  • (n.) Animation, as in discourse; ardor; fervency.
  • (n.) Sexual excitement in animals.
  • (n.) Fermentation.
  • (v. t.) To make hot; to communicate heat to, or cause to grow warm; as, to heat an oven or furnace, an iron, or the like.

  • (v. i.) To grow warm or hot by fermentation, or the development of heat by chemical action; as, green hay heats in a mow, and manure in the dunghill.
  • (imp. & p. p.) Heated; as, the iron though heat red-hot.
