Careful with money (7)
I believe the answer is:
thrifty
'careful with money' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for thrifty that I've seen before include "Careful with money" , "Not extravagant" , "Conserving" , "Frugal - economical" , "Careful and diligent in the use of resources" .)
