Packed whiskey when going in a hospital (5)
I believe the answer is:
awash
'packed' is the definition.
(thesaurus)
'whiskey when going in a hospital' is the wordplay.
'whiskey' becomes 'w' (alpha bravo charlie delta ...).
'when' becomes 'as'.
'going in' means one lot of letters goes inside another.
'hospital' becomes 'h'.
'w'+'as'='was'
'a'+'h'='ah'
'was' placed within 'ah' is 'AWASH'.
(Other definitions for awash that I've seen before include "becomes flooded" , "Partly under water" , "Flooded with water" , "Flood" , "Flooded; about to sink" .)
