Home in Northumbrian street? (4)
I believe the answer is:
nest
'home' is the definition.
(a bird's home)
'northumbrian street?' is the wordplay.
'northumbrian' becomes 'ne' (I am not sure about this - if you are sure you should believe this answer much more).
'street?' becomes 'st' (abbreviation).
'ne'+'st'='NEST'
'in' is the link.
Can you help me to learn more?
(Other definitions for nest that I've seen before include "Home of twigs, perhaps" , "Avian structure" , "Rook's residence?" , "Bird's retreat" , "Roost" .)
