Canvas shelter for an occupier (6)
I believe the answer is:
tenant
'occupier' is the definition.
(I know that tenant is a type of occupier)
'canvas shelter for an' is the wordplay.
'canvas' becomes 'tent' (I've seen this in other clues).
'shelter' indicates putting letters inside.
'for an' becomes 'na' (I am not sure about this - if you are sure you should believe this answer much more).
'tent' placed around 'na' is 'TENANT'.
Can you help me to learn more?
(Other definitions for tenant that I've seen before include "Person renting property" , "Lessee" , "Occupier but not owner" , "Resident" , "individual bound by lease" .)
