Tiny amount of money for exercise area's crazy (7)
I believe the answer is:
peanuts
'tiny amount of money' is the definition.
I can't judge whether this definition defines the answer.
'exercise area's crazy' is the wordplay.
'exercise' becomes 'pe' (Physical Education).
'area' becomes 'a' (maths abbreviation).
'crazy' becomes 'nuts' (nuts can informally mean crazy or mad).
'pe'+'a'+'nuts'='PEANUTS'
'for' acts as a link.
Can you help me to learn more?
(Other definitions for peanuts that I've seen before include "Very small amount of money" , "Bits of food" , "Trivial amount of money" , "Schulz cartoon; trifling sum" , "Schulz comic strip" .)
