Donne composed a lot (2,3)
I believe the answer is:
no end
'a lot' is the definition.
(I've seen this in another clue)
'donne composed' is the wordplay.
'composed' indicates anagramming the letters.
'donne' is an anagram of 'NO END'.
(Other definitions for no end that I've seen before include "Non-stop" , "Very much (slang)" , "A lot" , "detailed?" , "Without limit" .)
