Dare English students to return coins outside (9)
I believe the answer is:
challenge
'dare' is the definition.
(I've seen this before)
'english students to return coins outside' is the wordplay.
'english' becomes 'e' (abbreviation).
'students' becomes 'll' (an abbreviation for learner driver written twice).
'to return' shows that the letters should be reversed in order.
'coins' becomes 'change' (I've seen this in other clues).
'outside' means one lot of letters goes inside another.
'e'+'ll'='ell'
'ell' in reverse letter order is 'lle'.
'lle' going within 'change' is 'CHALLENGE'.
(Other definitions for challenge that I've seen before include "Issue an invitation to compete" , "difficult feat" , "Call something into question" , "Call to engage in a contest or fight" , "Invitation to duel" .)
