He gives the direction in the entrance (5)
I believe the answer is:
donor
'he gives' is the definition.
(I've seen this before)
'direction in the entrance' is the wordplay.
'direction' becomes 'N' (compass direction north).
'in the' indicates putting letters inside.
'entrance' becomes 'door' (door is a kind of entrance).
'n' put inside 'door' is 'DONOR'.
'the' acts as a link.
(Other definitions for donor that I've seen before include "One who gives, maybe blood" , "Organ giver?" , "Benefactor, giver" , "Maker of gift" , "Subscriber" .)
