Name of woman the Devil upended with triumphant expression (7)
I believe the answer is:
natasha
'name of woman' is the definition.
'devil upended with triumphant expression' is the wordplay.
'devil' becomes 'Satan' (synonyms).
'upended' says the letters should be written in reverse (in a down clue, letters go up).
'with' says to put letters next to each other.
'triumphant expression' becomes 'ha' (you might shout 'ha!' in triumph).
'satan' backwards is 'natas'.
'natas'+'ha'='NATASHA'
'the' is the link.
(Other definitions for natasha that I've seen before include "Russian girl's name" , "Tolstoy heroine" , "Woman" , "girl" .)
