Say one is in a rugged cove (5)
I believe the answer is:
voice
'say' is the definition.
(I know that voice is a type of say)
'one is in a rugged cove' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
an anagram of 'cove' is 'voce' which is located in the left over letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for voice that I've seen before include "Power of speaking" , "Sound with which one speaks" , "State" , "Sound of speech" , "right to have a say" .)
