hairs (plural count noun)

用法筆記

Unlike the uncountable noun 'hair' (which refers to a mass), 'hairs' is countable and points to individual strands. Use 'hairs' when you want to talk about a specific number of strands — for example, 'three grey hairs' or 'a few stray hairs'.

I washed my hair this morning.
💡For the mass of hair on your head, use the uncountable 'hair', not 'hairs'.
There is a hair in my soup' (when you mean one strand).
There is a hair in my soup
💡This is correct; 'a hair' is singular countable. ❌ 'There are hairs in my soup' — Only if you mean several strands.

by a hair

a hair's breadth

not by a hair

用法筆記

This sense is restricted to a small set of fixed expressions. 'By a hair' often follows verbs of narrowly achieving or missing something (win, lose, miss, escape). 'A hair's breadth' replaces 'hair' in the same pattern but is slightly more formal.

The difference is a hair's breadth.
💡Without 'breadth', the expression is incomplete. Use 'by a hair' as an adverbial phrase, not alone.
I missed the goal by hairs.
I missed the goal by a hair.
💡This sense uses the singular 'a hair', not the plural 'hairs'.
