How it's used
This character is almost exclusively used as a bound morpheme in scientific or culinary compounds rather than as a standalone verb. You will rarely encounter it outside of terms like 酵母 or 發酵. It functions as the core component for describing chemical processes involving microorganisms.
Examples
You must add yeast when making bread.

Common mistake
Learners often try to use 酵 as a standalone verb for fermenting, but it is not used that way in spoken Cantonese. Always use the full compound 發酵 when describing the process.
