Men must start with drinks (5)

Ross

I believe the answer is:

males

'men' is the definition.
(I've seen this in another clue)

'must start with drinks' is the wordplay.
'start with' suggests taking the first letters.
'drinks' becomes 'ales' (ale is a kind of drink).
The first letter of 'must' is 'm'.
'm'+'ales'='MALES'
