Crew has time for a drink (6)
I believe the answer is:
posset
'for a drink' is the definition.
(posset is a kind of drink)
'crew has time' is the wordplay.
I cannot really see how this works, but
'crew' could be 'posse' (I've seen this in another clue) and 'posse' is found within the answer.
'time' could be 't' (abbreviation) and 't' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for posset that I've seen before include "So step on curdled milk once used as a cold remedy" , "As relief for cold" , "Curdled milk drink" , "Sweet spiced milk curdled with alcohol" .)
