fermentation
C1Technical/Scientific, Formal, occasionally Literary (in metaphorical use).

Meaning
A chemical process in which microorganisms like yeast or bacteria break down organic substances (typically sugars) into simpler substances (like alcohol, acids, or gases), often producing energy and causing effervescence and heat.
Metaphorically, a state of agitation, excitement, or rapid development and change in ideas, creativity, or social conditions.
Linguistics
Semantic Notes

- Avoid direct association with 'брожение' only in negative social contexts ('ferment' can be neutral/positive in English).
- Do not confuse with 'fermentation' (process) and 'leaven'/'yeast' (agent).
Common Mistakes
- Misspelling as 'fermentaion' (missing 't').
- Using as a countable noun incorrectly (e.g., 'three fermentations' is correct only for types, not typically for the general process).
- Confusing 'fermentation' (anaerobic) with 'respiration' (aerobic).

FAQ
Frequently Asked Questions
No. While alcoholic fermentation is a common type, fermentation includes processes like lactic acid fermentation (yogurt, sauerkraut) and acetic acid fermentation (vinegar).
'Ferment' as a noun (/ˈfɜː.ment/) typically means a state of agitation or excitement ("in a ferment"). 'Fermentation' is the specific chemical/biological process. They are related but not interchangeable.
Yes. In its literal sense, it's a neutral technical term. Metaphorically, it can describe positive creative or intellectual energy (e.g., 'a fermentation of new ideas').
Fermentation, by strict biochemical definition, is an anaerobic (without oxygen) process. In common usage (e.g., 'fermentation crock'), it may refer to a process that can start aerobically but is completed anaerobically.
