UK royal composed war dance piece (6)
I believe the answer is:
edward
'uk royal' is the definition.
The definition suggests a singular noun which matches the answer.
'composed war dance piece' is the wordplay.
'piece' indicates the answer is hidden within the clue.
'EDWARD' is hidden in the letters of 'composed war dance'.
Can you help me to learn more?
(Other definitions for edward that I've seen before include "Name Lambert Simnel took when crowned" , "Male name" , "The Queen's youngest son" , "Lear, perhaps" , "The Black Prince's name" .)
