Allow directions and heading (7)
I believe the answer is:
entitle
'allow' is the definition.
(I've seen this before)
'directions and heading' is the wordplay.
'directions' becomes 'en' (east and north).
'and' is a charade indicator (letters next to each other).
'heading' becomes 'title' (title is a kind of heading).
'en'+'title'='ENTITLE'
(Other definitions for entitle that I've seen before include "Warrant" , "Licence" , "Give a right (to someone to do something)" , "Give a right or authority to" , "Give (someone) rights" .)
