Economical, thrifty (7)
I believe the answer is:
sparing
This clue is a double definition.
'economical' is the first definition.
(I know that economical can be written as sparing)
'thrifty' is the second definition.
(similar in meaning)
(Other definitions for sparing that I've seen before include "mean" , "Economic (with resources)" , "Moderate, economical" , "Thrifty" , "Scanty - merciful" .)
