American small change being found in school is dodgy (7)
I believe the answer is:
suspect
'dodgy' is the definition.
(I've seen this before)
'american small change being found in school' is the wordplay.
'american' becomes 'us'.
'small change' becomes 'p'.
'being found in' indicates putting letters inside.
'school' becomes 'sect' (I've seen this before**).
'us'+'p'='usp'
'usp' put into 'sect' is 'SUSPECT'.
'is' acts as a link.
(Other definitions for suspect that I've seen before include "Presume" , "Dodgy" , "Doubt - man being questioned by police" , "Person being accused" , "Doubt truth of" .)
