Steep for a heavy drinker (4)
I believe the answer is:
soak
This clue could be a double definition.
'steep' is the first definition.
(I've seen this in another clue)
'heavy drinker' is the second definition.
'soak' can be an answer for 'drinker' (thesaurus). I'm not certain of the 'heavy' bit.
'for a' is the link.
Can you help me to learn more?
(Other definitions for soak that I've seen before include "Make thoroughly wet" , "Douse, drench" , "Make extremely wet" , "Get wet" , "Steep in liquid" .)
