The blokes who join me at the Nag's Head (3)
I believe the answer is:
men
'the blokes who join' is the definition.
'men' can be an answer for 'the blokes' (I've seen this in another clue). I'm not certain of the rest of the definition.
'me at the nag's head' is the wordplay.
'at' means one lot of letters go next to another.
'head' suggests taking the first letters.
The first letter of 'nags' is 'n'.
'me'+'n'='MEN'
Can you help me to learn more?
(Other definitions for men that I've seen before include "Adult males" , "Human males" , "Soldiers" , "Crew" , "- - -o'-war (ships)" .)
