Not odd, being a Scot, to make law (5)
I believe the answer is:
enact
'make law' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for enact that I've seen before include "Make (a bill) law" , "Authorize" , "Put into practice" , "Present" , "Official order" .)
