It may have been spent in Israel (6)
I believe the answer is:
shekel
'it may have been spent in israel' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for shekel that I've seen before include "One is equal to 100 agorot" , "Israeli monetary unit" , "Small price" , "Israeli coin" , "Basic unit of money in Israel" .)
