They certainly put you in your place! (6)
I believe the answer is:
ushers
'they' is the definition.
Both the answer and definition are plural nouns.
Perhaps you can see an association between them that I don't see?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for ushers that I've seen before include "Escorts" , "Court officials" , "They escort people to seats" , "Wedding helpers" , "Theatre attendants" .)
