Frightened by a corpse? (6,5)
I believe the answer is:
scared stiff
'frightened by a corpse?' is the definition.
I know nothing about this answer so I can't tell whether this works.
'frightened by a corpse?' is the wordplay.
'frightened' becomes 'scared' (scared means frightened or fearful).
'by' is a charade indicator (letters next to each other).
'a corpse?' becomes 'stiff' ('stiff' can be a synonym of 'corpse').
'scared'+'stiff'='SCARED STIFF'
Can you help me to learn more?
(Other definitions for scared stiff that I've seen before include "Petrified" , "Frightened to death!" .)
