Evict some of the obstreperous tenants (4)
I believe the answer is:
oust
'evict' is the definition.
(I've seen this before)
'some of the obstreperous tenants' is the wordplay.
'some of' says the answer is hidden in the clue.
'OUST' is hidden in the letters of 'obstreperous tenants'.
(Other definitions for oust that I've seen before include "Unseat" , "Drive out, expel" , "Turf out" , "Send packing" , "Remove from a position or office" .)
