Guys make a hole in one big stick (6)
I believe the answer is:
menace
'big stick' is the definition.
Both the answer and definition are singular nouns.
Maybe they are linked in a way I don't understand?
'guys make a hole in one' is the wordplay.
'guys' becomes 'men' (guy can mean a man).
'make a hole in one' becomes 'ace' (I've seen this in another clue).
'men'+'ace'='MENACE'
Can you help me to learn more?
(Other definitions for menace that I've seen before include "Intimidation" , "Threat; threaten" , "Threaten with harm or danger" , "Serious threat" , "Threaten with violence" .)
