Etymology: "Yeasted" is a simple formation: the noun "yeast" with the suffix "-ed" attached, producing an adjective meaning made to rise. Yeast itself is the older and more surprising piece of the story. It comes from Old English "gist" or "giest," a word for the foam or froth that forms on fermenting liquid, and it entered the language as the name for that froth long before anyone understood that living microorganisms were behind the leavening of bread and the fermenting of beer. The suffix does the rest of the work. Adding "-ed" to a noun like this turns it into a description of something that has been treated with, or made to contain, that substance. A yeasted dough is one that has had yeast added to it, so it is the familiar sense of bread rising under the action of that living foam.

Synonyms: fermented, leavened
