Row after boss gets a title (8)
I believe the answer is:
headline
'a title' is the definition.
(thesaurus)
'row after boss' is the wordplay.
'row' becomes 'line' (I've seen this before).
'after' is a charade indicator (letters next to each other).
'boss' becomes 'head' ('head' can be a synonym of 'boss').
'line' after 'head' is 'HEADLINE'.
'gets' acts as a link.
(Other definitions for headline that I've seen before include "streamer, perhaps" , "Prominent text" , "Article title" , "star" , "Newspaper title" .)
