Coin another term for school with no restrictions (5)
I believe the answer is:
ducat
'coin another term' is the definition.
'ducat' can be an answer for 'coin' (thesaurus). I'm unsure of the 'another term' bit.
'school with no restrictions' is the wordplay.
'school' becomes 'educate' ('educate' can be a synonym of 'school').
'with no restrictions' says to take the centre.
The centre of 'educate' is 'DUCAT'.
'for' is the link.
(Other definitions for ducat that I've seen before include "Former Eur. gold coin" , "Old European gold or silver coin" , "Historical coin" , "Antique coin" , "Formerly a gold coin of several European countries" .)
