Evict number of people (7)
I believe the answer is:
turnout
'evict' is the definition.
(I've seen this before)
'number of people' is the wordplay.
'number' becomes 'turn' (synonyms).
'of people' becomes 'out' (I can't justify this - if you can you should believe this answer much more).
'turn'+'out'='TURNOUT'
Can you help me to learn more?
(Other definitions for turnout that I've seen before include "Expel" , "Muster" , "number of people coming to meeting" , "Number of people who come to a function, or their dress" , "number of people present" .)
