Pass law allowing cane to be brought back and used by head teachers (5)
I believe the answer is:
enact
'pass law' is the definition.
(I've seen this before)
'cane to be brought back and used by head teachers' is the wordplay.
I cannot quite understand how this works, but
an anagram of 'cane' is 'enac' which is located in the answer.
A single letter 't' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'allowing' acts as a link.
Can you help me to learn more?
(Other definitions for enact that I've seen before include "Authorize" , "Decree" , "Establish by law - perform" , "Ordain" , "Official order" .)
