Move forgotten, lady finally caught by male dancer (6,7)
I believe the answer is:
margot fonteyn
'dancer' is the definition.
(I know that Margot Fonteyn was a dancer)
'move forgotten lady finally caught by male' is the wordplay.
'move' is an anagram indicator (I've seen 'moving' mean this).
'finally' indicates one should take the final letters.
'caught by' means one lot of letters goes inside another.
'male' becomes 'man' (man is a kind of male).
The final letter of 'lady' is 'y'.
'forgotten'+'y'='forgotteny'
'forgotteny' anagrammed gives 'rgotfontey'.
'rgotfontey' placed inside 'man' is 'MARGOT FONTEYN'.
(Other definitions for margot fonteyn that I've seen before include "Ballerina; not many forget (anag.)" , "Dame __, English ballerina, d. 1991" .)
