Accountant having chat about women’s modelling area (7)
I believe the answer is:
catwalk
'modelling area' is the definition.
(models walk down catwalks)
'accountant having chat about women's' is the wordplay.
'accountant' becomes 'CA' (abbreviation for chartered accountant).
'having' says to put letters next to each other.
'chat' becomes 'talk' (I've seen this in another clue).
'about' is an insertion indicator.
'women' becomes 'w' (standard abbreviation).
'talk' placed around 'w' is 'twalk'.
'ca'+'twalk'='CATWALK'
(Other definitions for catwalk that I've seen before include "Model's place of work?" , "runway" , "Where models parade" , "Where models are found" , "Models' pathway" .)
