Something explosive about a woman occupant (6)
I believe the answer is:
tenant
'occupant' is the definition.
(I know that tenant is a type of occupant)
'something explosive about a woman' is the wordplay.
'something explosive' becomes 'tnt' (I can't explain this - if you can you should give a lot more credence to this answer).
'about' means one lot of letters goes inside another.
'a woman' becomes 'ena' (woman's name).
'tnt' going around 'ena' is 'TENANT'.
Can you help me to learn more?
(Other definitions for tenant that I've seen before include "Occupier but not owner" , "Lodger" , "One renting property" , "One occupying rented property" , "he or she rents" .)
