IPA: /ˈjiːstlaɪk/
KK: /jistlaɪk/
Having qualities or characteristics similar to yeast, often in terms of fermentation or growth.
The dough had a yeastlike texture, making it rise beautifully during baking.
Yeastlike → It is formed from "yeast" (from Old English *gist*, meaning a fermenting agent) and "-like" (meaning resembling or similar to). The word "yeastlike" describes something that resembles or has characteristics of yeast, particularly in its ability to ferment or rise.
Think of something that is 'similar to' ('-like') a 'fermenting agent' ('yeast') — that's why yeastlike refers to something that has qualities of yeast.
