Sort of posh, neat carriage (8)
I believe the answer is:
stanhope
'carriage' is the definition.
(thesaurus)
'sort of posh neat' is the wordplay.
'sort of' indicates anagramming the letters.
'posh'+'neat'='poshneat'
'poshneat' anagrammed gives 'STANHOPE'.
(Other definitions for stanhope that I've seen before include "Light horse-drawn carriage; Nineteen across (anag.)" , "vehicle" , "Phaetons can be turned into a light open one-seater carriage" , "carriage that has seat only for one" , "It may have only two wheels" .)
