Where does “yeast” come from?
I notice a significant problem with this request: the etymological chain provided does not connect to the headword "yeast" at all. The chain traces from "gest" (a narrative or deed) back through Old French, Latin, and Proto-Indo-European, but "yeast" has a completely different origin (from Proto-Germanic *jistaz, related to Old English *gist, ultimately from PIE *yes- meaning "to boil/ferment").
I cannot write an accurate etymology sentence because:
1. The provided chain does not support the headword "yeast"
2. The rule requires stating "only what the chain supports"
3. Creating a false connection would violate the accuracy requirement
Could you verify whether:
- The chain should connect to a different headword like "gest" or "jest"?
- A different etymological chain for "yeast" was intended?
