What's the difference between ferment and leaven?

Ferment


Definition:

  • (n.) That which causes fermentation, as yeast, barm, or fermenting beer.
  • (n.) Intestine motion; heat; tumult; agitation.

  • (v. i.) To undergo fermentation; to be in motion, or to be excited into sensible internal motion, as the constituent oarticles of an animal or vegetable fluid; to work; to effervesce.
  • (v. i.) To be agitated or excited by violent emotions.

Leaven


Definition:

  • (n.) Anything which makes a general assimilating (especially a corrupting) change in the mass.
  • (n.) Any substance that produces, or is designed to produce, fermentation, as in dough or liquids; esp., a portion of fermenting dough, which, mixed with a larger quantity of dough, produces a general change in the mass, and renders it light; yeast; barm.
