Fit, we hear, for a drop of the hard stuff? (4)
I believe the answer is:
hail
'a drop of the hard stuff?' is the definition.
(I've seen this before)
'fit we hear' is the wordplay.
'fit' becomes 'hale' (both can mean healthy).
'we hear' indicates a 'sounds like' (homophone) clue.
'hale' is a homophone of 'HAIL'.
'for' acts as a link.
(Other definitions for hail that I've seen before include "Call for - praise, vociferously" , "Greet - bad weather" , "Shower of ice pellets" , "come down hard" , "Old Roman salute, or frozen pellets" .)
