Word Confusion: Ferment versus Foment

In one way ferment vs foment are similar — they both are used to describe an agitation or stirring up of people.

They diverge in their other meanings.

Ferment also refers to an anaerobic process that uses living organisms like yeasts, molds, and certain bacterias to instigate a chemical process that breaks down sugars. It’s a process used in making pickles and alcohols, including beer.

Foment has a more archaic definition by which doctors recommended using warmth to relieve aches and injuries. Well, nothing much has changed there . . .
