Male type, terribly quiet? (7)
I believe the answer is:
milksop
'male' is the definition.
(I have seen 'Feeble male' mean 'milksop' so perhaps 'male' could also mean 'milksop')
'type terribly quiet?' is the wordplay.
'type' becomes 'milk' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'terribly' becomes 'so' (both can mean 'extremely').
'quiet?' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'milk'+'so'+'p'='MILKSOP'
Can you help me to learn more?
(Other definitions for milksop that I've seen before include "Feeble male" , "Weak or effeminate man" , "Feeble youth" , "Feeble and effete person" , "Cissy (informal) -- limps OK (anag)" .)
