Some insects occupying people (7)
I believe the answer is:
tenants
'occupying people' is the definition.
'tenants' can be an answer for 'people' (tenant is a kind of person). I am unsure of the 'occupying' bit.
'some insects' is the wordplay.
'some' becomes 'ten' (I can't explain this - if you can you should give a lot more credence to this answer).
'insects' becomes 'ants' (ant is a kind of insect).
'ten'+'ants'='TENANTS'
Can you help me to learn more?
(Other definitions for tenants that I've seen before include "Occupiers" , "They pay rent" , "residents" , "Lodgers" .)
