Express remorse for terrible sepia logo (9)
I believe the answer is:
apologise
'express remorse for terrible sepia logo' is the definition.
I can't judge whether this definition defines the answer.
'terrible sepia logo' is the wordplay.
'terrible' indicates anagramming the letters.
'sepia'+'logo'='sepialogo'
'sepialogo' with letters rearranged gives 'APOLOGISE'.
Can you help me to learn more?
(Other definitions for apologise that I've seen before include "Recognise fault" , "put things straight" , "Acknowledge failings" , "Say one is sorry" , "Say sorry, my fault" .)
