It is clear in composition and practical (9)
I believe the answer is:
realistic
'practical' is the definition.
(associated in meaning)
'it is clear in composition' is the wordplay.
'in composition' indicates anagramming the letters (I've seen this in other clues).
'it'+'is'+'clear'='itisclear'
'itisclear' is an anagram of 'REALISTIC'.
'and' acts as a link.
(Other definitions for realistic that I've seen before include "Practicable" , "Pragmatic" , "It is clear (anag)" , "accurate picture" , "believable" .)
