Discover the length of stately dance (7)
I believe the answer is:
measure
'dance' is the definition.
(I've seen this in other clues)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for measure that I've seen before include "Get hands, perhaps" , "amount of drink" , "Determine the size of" , "Shakespeare play: ''Measure for . . . . . . .''" , "Evaluate; ruler" .)
