The damaged part looks very red, outwardly (4)
I believe the answer is:
edam
'looks very red outwardly' is the definition.
I can't tell whether this defines the answer.
'the damaged part' is the wordplay.
'part' says the answer is hidden in the clue.
'EDAM' is hidden in the letters of 'the damaged'.
Can you help me to learn more?
(Other definitions for edam that I've seen before include "Dutch specialty" , "Hard Dutch cheese" , "Dutch food" , "Made into popular cheese" , "Spherical cheese" .)
