Drunk-sounding gentleman in Dorset for example (5)
I believe the answer is:
shire
'dorset for example' is the definition.
I can't judge whether this definition defines the answer.
'drunk-sounding gentleman in' is the wordplay.
'drunk-sounding' becomes 'h' (I am not sure about this - if you are sure you should believe this answer much more).
'gentleman' becomes 'sire'.
'in' is an insertion indicator.
'h' put into 'sire' is 'SHIRE'.
(Other definitions for shire that I've seen before include "Berks" , "Powerful draught horse" , "Breed of draught horse" , "The -----: Tolkien's hobbit-land" , "Rural county" .)
