Cover wound in black and get on (7)
I believe the answer is:
bandage
'cover wound' is the definition.
'bandage' can be an answer for 'cover' (I have seen 'medical cover' mean 'bandage' so perhaps 'cover' could also mean 'bandage'). I am not certain of the 'wound' bit.
'black and get on' is the wordplay.
'black' becomes 'b' (as in pencil classifications).
'get on' becomes 'age' (synonyms).
'b'+'and'+'age'='BANDAGE'
'in' is the link.
Can you help me to learn more?
(Other definitions for bandage that I've seen before include "Injury protection" , "Wrap for a wound" , "Material for wound or injury" , "First-aid item" , "Dressing for wounds" .)
