Sensible, practical (9)
I believe the answer is:
realistic
This clue is a double definition.
'sensible' is the first definition.
(I've seen this before)
'practical' is the second definition.
(associated in meaning)
(Other definitions for realistic that I've seen before include "Objective" , "It is clear, being practical and sensible" , "Lifelike" , "believable" , "Practical; true to life" .)
