Stylish article written after member appears in film (7)
I believe the answer is:
elegant
'stylish' is the definition.
(both can mean fancy or ornate)
'article written after member appears in film' is the wordplay.
'article' becomes 'an' (indefinite article).
'written after' means one lot of letters go next to another.
'member' becomes 'leg' (member can mean a limb).
'appears in' indicates putting letters inside.
'film' becomes 'ET' (E.T. the Extra-Terrestrial).
'an' after 'leg' is 'legan'.
'legan' inserted within 'et' is 'ELEGANT'.
(Other definitions for elegant that I've seen before include "A gentle sort of stylish appearance" , "Well-dressed" , "Attractive and graceful or stylish" , "Refined gracefulness" , "Debonair, stylishly dressed" .)
