Messenger given entrance into shelter (7)
I believe the answer is:
legatee
'messenger' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'entrance into shelter' is the wordplay.
'entrance' becomes 'gate' (type of entrance).
'into' is an insertion indicator.
'shelter' becomes 'lee' (as in lee side, the side sheltered from wind).
'gate' placed into 'lee' is 'LEGATEE'.
'given' is the link.
Can you help me to learn more?
(Other definitions for legatee that I've seen before include "one remembered" , "person entitled to benefit" , "Person receiving a bequest" , "One receiving legacy" , "Gifted person" .)
