Make law on corporal punishment turn teacher's head (5)
I believe the answer is:
enact
'make law' is the definition.
(I've seen this in another clue)
'corporal punishment turn teacher's head' is the wordplay.
'corporal punishment' becomes 'cane' (I've seen this before. I am not sure about the 'corporal' bit.).
'turn' says the letters should be written in reverse.
'head' suggests taking the first letters.
The first letter of 'teachers' is 't'.
'cane' back-to-front is 'enac'.
'enac'+'t'='ENACT'
'on' acts as a link.
Can you help me to learn more?
(Other definitions for enact that I've seen before include "Official order" , "get into law" , "Put on stage or statute book" , "Make (a bill) law" , "Authorize" .)
