Cyril's fancy words (6)
I believe the answer is:
lyrics
'words' is the definition.
(I've seen this in another clue)
'cyril's fancy' is the wordplay.
'fancy' is an anagram indicator.
'cyrils' is an anagram of 'LYRICS'.
(Other definitions for lyrics that I've seen before include "words to perform" , "Words of a pop song" , "Words used in songs" , "words in numbers" , "Short song-like poems" .)
