Money makes stupid points (5)
I believe the answer is:
dimes
'money makes' is the definition.
The definition and answer can be both related to change as well as being verbs in their -s form.
Perhaps you can see a link between them that I can't see?
'stupid points' is the wordplay.
'stupid' becomes 'dim' (similar in meaning).
'points' becomes 'Es' (two compass points).
'dim'+'es'='DIMES'
Can you help me to learn more?
(Other definitions for dimes that I've seen before include "Tenths of a dollar" , "US ten-cent coins" , "$0.10n (n>1)" , "Ten cent pieces" , "Tenths of dollars" .)
