Job taken up by a tenant (10)
I believe the answer is:
occupation
'job' is the definition.
(I've seen this before)
'up by a tenant' is the wordplay.
I cannot really see how this works, but
'up' is within the answer.
'by' could be 'at' and 'at' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'taken' acts as a link.
Can you help me to learn more?
(Other definitions for occupation that I've seen before include "Calling" , "the seizure and control of a foreign territory" , "period of residency" , "Job, profession" , "end of invasion?" .)
