Time to dance the minuet (6)
I believe the answer is:
minute
'time' is the definition.
(thesaurus)
'dance the minuet' is the wordplay.
'dance' indicates anagramming the letters (I've seen this in other clues).
'minuet' anagrammed gives 'MINUTE'.
'to' is the link.
(Other definitions for minute that I've seen before include "Very small, like unit of time" , "Little -- 60 18 across" , "Measure of time" , "barely noticeable?" , "microscopic" .)
