A song from Cyril (5)
I believe the answer is:
lyric
'a song' is the definition.
(song with lyrics)
'from cyril' is the wordplay.
'from' is an anagram indicator (the anagram comes from the same letters).
'cyril' anagrammed gives 'LYRIC'.
(Other definitions for lyric that I've seen before include "Airline" , "A song or poem" , "Of poetry that expresses the poet's feelings" , "Song's words" , "Short poem of songlike quality" .)
