Perhaps facing north and then east in turn (6)
I believe the answer is:
veneer
'perhaps facing' is the definition.
'veneer' can be an answer for 'facing' (I've seen this before). I am not sure about the 'perhaps' bit.
'north and then east in turn' is the wordplay.
'north' becomes 'N' (abbreviation).
'and then' means one lot of letters go next to another (I've seen this in other clues).
'east' becomes 'e' (abbreviation).
'in' indicates putting letters inside.
'turn' becomes 'veer' (veering is a kind of turning).
'n'+'e'='ne'
'ne' put into 'veer' is 'VENEER'.
Can you help me to learn more?
(Other definitions for veneer that I've seen before include "Thin layer on surface, often of furniture" , "Face" , "Thin covering of expensive wood on furniture" , "Thin layer glued to the top" , "Superficial veneer" .)
