Order it officially for new road going up north (6)
I believe the answer is:
ordain
'order' is the definition.
(I know that order can be written as ordain)
'new road going up north' is the wordplay.
'new' indicates an anagram.
'going' becomes 'ni' (I can't explain this - if you can you should believe this answer much more).
'up north' says the letters should be written in reverse (like on a map - reverse order in down clue).
'ni' in reverse letter order is 'in'.
'road' is an anagram of 'orda'.
'orda'+'in'='ORDAIN'
'it officially for' acts as a link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for ordain that I've seen before include "Make a decree" , "Decree and admit to holy orders" , "Decree authoritatively" , "Decree or appoint to priesthood" , "Appoint as priest" .)
