She is given two articles set in a case (7)
I believe the answer is:
sheathe
'a case' is the definition.
(thesaurus)
'she is given two articles' is the wordplay.
'two articles' can mean two replacements for 'article'.
'is given' is a charade indicator (letters next to each other).
'article' becomes 'a' (English indefinite article).
'article' becomes 'the' (the definite article in English).
'she'+'a'+'the'='SHEATHE'
'set in' acts as a link.
(Other definitions for sheathe that I've seen before include "Put away (a sword)" , "Put (a sword) it its cover" , "Cover in case" , "Put (a sword) into its holder" , "Encase in protection" .)
