Use less money: remove penny (5)
I believe the answer is:
skimp
'use less money remove penny' is the definition.
I can't judge whether this definition defines the answer.
'remove penny' is the wordplay.
'remove' becomes 'skim' (skimming is a kind of removing).
'penny' becomes 'p' (short for pence).
'skim'+'p'='SKIMP'
Can you help me to learn more?
(Other definitions for skimp that I've seen before include "Try to economise" , "Act hastily" , "Spend not enough time and care on (job)" , "Withhold" , "Stint in order to economise" .)
