Person who gives way in the entrance (5)
I believe the answer is:
donor
'person who' is the definition.
'donor' can be an answer for 'person' (donor is a kind of person). I am not sure about the remainder of the definition.
'way in the entrance' is the wordplay.
'way' becomes 'n' (Compass direction - North).
'in' is an insertion indicator.
'the entrance' becomes 'door' (door is a kind of entrance).
'n' put into 'door' is 'DONOR'.
'gives' acts as a link.
Can you help me to learn more?
(Other definitions for donor that I've seen before include "Organ giver?" , "Someone providing" , "One who dishes out" , "Maker of gift" , "blessed person, relatively" .)
