Feedback vs. Feedbacks
In ordinary general English, “feedback” is treated as an uncountable noun, so “some feedback,” “pieces of feedback,” or “comments” is normally clearer than “feedbacks.” Specialized technical fields may define countable uses, but those do not change the general-writing default.
For ordinary comments, reactions, or advice, use “feedback” without a plural -s. If you need to count items, write “pieces of feedback,” “comments,” or another countable noun.
Key details
Choose the right form
| Meaning / situation | Form / construction | Decision |
|---|---|---|
| ordinary comments, reactions, or advice as a mass noun | feedback | Use the uncountable form. |
| individual countable items | pieces of feedback / comments / responses | Use a countable unit rather than ordinary plural “feedbacks.” |
| specialized technical senses | check domain convention | Do not generalize the everyday mass-noun rule to every specialist use without evidence. |
Quick tests
Meaning / construction test
Are you referring to ordinary evaluative comments or reactions?
If yes: Use “feedback” without plural -s.
If no: If you need a count, name the units: “three pieces of feedback,” “three comments,” or another precise noun.
Caveat: This guide addresses ordinary English use. Specialist engineering or systems contexts can use technical terminology differently and should follow domain conventions.

Counting
To count separate items, use wording such as “three comments” or “three pieces of feedback.”
General Rule
