Funk from a person by boisterous area of town (7)
I believe the answer is:
borough
'area of town' is the definition.
'funk from a person by boisterous' is the wordplay.
'funk from a person' becomes 'bo' (short for body odour).
'by' says to put letters next to each other.
'boisterous' becomes 'rough' (synonyms).
'bo'+'rough'='BOROUGH'
(Other definitions for borough that I've seen before include "London district" , "Local district" , "Administrative area" , "Town with a corporation and special privileges" , "Important town" .)
