2.nounB2

pattern: wear many hats for multiple roles

pattern: in one's hat as [role] for official capacity

Common collocations
  • wear many hats
  • wear several hats
  • change hats
  • switch hats
  • in one's hat as
  • put on a different hat
Synonyms
  • role

    the general term for the function a person performs in a particular situation; broader and more formal than 'hat'

  • position

    a specific job or official rank within an organization; more formal and not metaphorical

  • capacity

    formal synonym for 'role,' often used in 'in one's capacity as [role]'

Grammar Patterns

wear + [number/several/many] + hats

change hats

in one's hat as + [role]

Usage Note

This sense is almost always used in fixed expressions such as wear many hats, change hats, or in one's hat as [role]. It is not used as a standalone countable noun (❌ 'She has a new hat' for 'She has a new role'). The metaphor comes from the idea that different official positions in history had distinct headwear, so a person 'wearing a different hat' means they are acting in a different capacity.

Common Mistakes

I have a new hat as team leader.
I am wearing a new hat as team leader.
The sense requires 'wear' or 'have on' the hat metaphorically, not 'have a hat.'

Etymology

Proto-GermanicOld EnglishMiddle EnglishEnglish

The word hat comes from Old English hæt, which meant a covering for the head. It traces back to the Proto-Germanic word *hattuz, which is related to the word hood. The metaphorical use of hat to mean a person's role or job responsibility dates from the 1800s, based on the idea that different official positions once had their own distinct headwear — a judge's hat, a bishop's hat, a soldier's hat.
