When young woman briefly returned for a dance (5)
I believe the answer is:
salsa
'a dance' is the definition.
(I've seen this before)
'when young woman briefly returned' is the wordplay.
'when' becomes 'as'.
'young woman' becomes 'lass' (lass is a kind of young woman).
'briefly' means to remove the last letter.
'returned' is a reversal indicator.
'as'+'lass'='aslass'
'aslass' with its last letter taken off is 'aslas'.
'aslas' backwards is 'SALSA'.
'for' acts as a link.
(Other definitions for salsa that I've seen before include "Spicy tomato sauce" , "Tomato relish" , "Latin-American dance" , "This could be hot" , "Latin American dance - spicy Mexican sauce" .)
