The chaps make me the new head (3)
I believe the answer is:
men
'the chaps' is the definition.
(I've seen this before)
'me the new head' is the wordplay.
'head' says to take the initial letters.
The first letter of 'new' is 'n'.
'me'+'n'='MEN'
'make' acts as a link.
(Other definitions for men that I've seen before include "'So many ..., so many opinions'" , "Crew" , "Human males" , "Chess pieces" , "Males of Armenian extraction." .)
