Hid in Crimson Bay? No, the other way round (7)
I believe the answer is:
covered
'hid' is the definition.
(covering is a kind of hiding)
'crimson bay? no the other way round' is the wordplay.
I cannot quite understand how this works, but
'crimson' could be 'red' (synonyms) and 'red' is located in the answer.
'bay?' could be 'cove' (I've seen this in another clue) and 'cove' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'in' acts as a link.
Can you help me to learn more?
(Other definitions for covered that I've seen before include "Travelled (a distance); protected" , "Concealed; roofed over" , "given protection" , "Concealed; dealt with" , "Insured; enveloped" .)
