Common, Ravel's composition, after college (9)
I believe the answer is:
universal
'common' is the definition.
(I've seen this before)
'ravel's composition after college' is the wordplay.
'composition' is an anagram indicator (letters arranged or composed in a different order).
'after' is a charade indicator (letters next to each other).
'college' becomes 'uni' (short for university).
'ravels' anagrammed gives 'versal'.
'versal' after 'uni' is 'UNIVERSAL'.
(Other definitions for universal that I've seen before include "Applicable to all cases" , "blanket" , "Of worldwide scope" , "wide-ranging and comprehensive" , "All-inclusive" .)
