It's clear I possibly could become pragmatic (9)
I believe the answer is:
realistic
'pragmatic' is the definition.
(I've seen this before)
'it's clear i possibly' is the wordplay.
'possibly' indicates an anagram.
'its'+'clear'+'i'='itscleari'
'itscleari' anagrammed gives 'REALISTIC'.
'could become' acts as a link.
(Other definitions for realistic that I've seen before include "Level-headed" , "Pragmatic" , "Down-to-earth" , "Practicable" , "Faithful" .)
