The word "yeast" has existed in English for as long as the language has
existed. Spellings have varied over time ? in Middle English it was "yest"
and in Old English "gist" or "geist" ? but the word's meaning has remained
basically the same for centuries. in its earliest documented uses, "yeast"
referred to a creamy or yellowish froth that forms on the top of fermented
beverages such as beers or ales (not surprising, given that one of the
first commercial uses of yeast was in the preparation of such drinks), and
that sense is still used today. In its first documented English uses in the
1500s, the adjective "yeasty" described people or things with a similarly
yellowish or frothy appearance.
