A new resident in shelter one rents (6)
I believe the answer is:
tenant
'a new resident' is the definition.
'tenant' can be an answer for 'resident' (tenant is a kind of resident). I am unsure of the 'a new' bit.
'shelter one rents' is the wordplay.
I cannot quite see how this works, but
'one' could be 'an' (an apple is one apple) and 'an' is found within the answer.
'shelter' could be 'tent' (a tent is a kind of shelter) and 'tent' is located in the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for tenant that I've seen before include "Person renting property" , "Renting occupant" , "one paying rent" , "Lessee" , "Anne Bronte's novel 'The ...... of Wildfell Hall'" .)
