Online winner is one likely take tenants out (7)
I believe the answer is:
evictor
'one likely take tenants out' is the definition.
I can't tell whether this defines the answer.
'online winner' is the wordplay.
'online' becomes 'e' (as in e-mail or e-commerce).
'winner' becomes 'victor' (synonyms).
'e'+'victor'='EVICTOR'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for evictor that I've seen before include "who puts an end to occupation?" , "One who boots out" , "one dispossesses by law" , "One chucks out" , "Bailiff" .)
