A one night stand, perhaps (3)
I believe the answer is:
gig
This clue could be a double definition.
'a one night' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'stand perhaps' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?
Can you help me to learn more?
(Other definitions for gig that I've seen before include "Live musical performance" , "A single musical performance - it's a palindrome" , "A palindromic one-night performance" , "A one-night engagement for entertainer" , "One-night stand" .)
