Cape of pianist without sleeves turned up (5)
I believe the answer is:
sinai
'cape' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'pianist without sleeves turned up' is the wordplay.
'SINAI' is hidden backwards in amongst the letters.
However, I'm not sure how the hidden word is indicated.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for sinai that I've seen before include "Egyptian location" , "Mount on which Moses received the Ten Commandments" , "One showing genetic change" , "Deserted area" , "Egyptian desert" .)
