Last couple returned in a short time for dance (6)
I believe the answer is:
minuet
'for dance' is the definition.
(minuet is a kind of dance)
'last couple returned in a short time' is the wordplay.
I cannot quite understand how this works, but
'last' could be 't' (I've seen this in other clues) and 't' is present in the answer.
'in' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for minuet that I've seen before include "18th-century dance" , "Stately old dance, takes only a minute" , "Stately C 18 dance" , "Gracious old dance, just takes a minute" , "Slow, graceful dance" .)
