Chaps who join me at the Nag's Head (3)
I believe the answer is:
men
'chaps who join' is the definition.
'men' can be an answer for 'chaps' (chap means a man). I am unsure of the rest of the definition.
'me at the nag's head' is the wordplay.
'at' says to put letters next to each other.
'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 "Males of Armenian extraction." , "Human males" , "Adult males" , "- - -o'-war (ships)" , "Fellows, chaps" .)
