The tenant's occupation (6)
I believe the answer is:
tenure
This clue could be a double definition.
'the tenant's' is the first definition.
Although both the answer and definition are singular nouns, I cannot see how one could define the other.
'occupation' is the second definition.
(I've seen this before)
Can you help me to learn more?
(Other definitions for tenure that I've seen before include "Neuter (anag)" , "Permanent employment right" , "Length of time in office" , "Right or period to hold, university post say" , "Term for which to hold a position" .)
