Crossword Genius

Biographical sketch is for dossier (7)

Ross

I believe the answer is:

profile

'biographical sketch' is the definition.
(thesaurus)

'for dossier' is the wordplay.
'for' becomes 'pro' (as in being 'pro' something).
'dossier' becomes 'file' (a dossier is a file or set of information).
'pro'+'file'='PROFILE'

'is' is the link.

(Other definitions for profile that I've seen before include "Sideways view" , "Sideways outline" , "View from one side" , "image" , "Short biographical sketch" .)

I've seen this clue in The Guardian.
