Really cool hospital given smallest cash amount? (3)
I believe the answer is:
hip
'really cool' is the definition.
(hip can mean fashionable)
'hospital given smallest cash amount?' is the wordplay.
'hospital' becomes 'h'.
'given' says to put letters next to each other.
'smallest cash amount?' becomes 'ip' (resembles 1p, one pence).
'h'+'ip'='HIP'
(Other definitions for hip that I've seen before include "Rose fruit; start of cheer" , "Slangily stylish like rose fruit" , "Pelvis" , "flask here?" , "Fashionable" .)
