Scant cover left over in hospital to hide lump (9)
I believe the answer is:
loincloth
'scant cover' is the definition.
(garment providing only a little coverage)
'left over in hospital to hide lump' is the wordplay.
'left over' becomes 'lo' (this might be a standard abbreviation of which I'm unaware).
'hospital' becomes 'h'.
'to hide' is an insertion indicator.
'lump' becomes 'clot'.
'in'+'h'='inh'
'inh' enclosing 'clot' is 'incloth'.
'lo'+'incloth'='LOINCLOTH'
Can you help me to learn more?
(Other definitions for loincloth that I've seen before include "Minimal garment" , "Garment Indian may have" , "Minimum clothing?" , "this is placed round middle of groin?" , "Simple garment" .)
