Re-number this place (4)
I believe the answer is:
reno
'place' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see an association between them that I can't see?
're-number' is the wordplay.
'number' becomes 'no' (abbreviation for 'number').
're'+'no'='RENO'
'this' acts as a link.
Can you help me to learn more?
(Other definitions for reno that I've seen before include "US divorce centre" , "US gambling resort" , "Nevada marriage and divorce centre" , "City in Nevada known for gambling and easy marriage/divorce" , "City in Nevada noted for quickie divorces" .)
