Dance move will essentially fall in place (9)
I believe the answer is:
saltation
'dance move will' is the definition.
The definition suggests a singular noun which matches the answer.
'essentially fall in place' is the wordplay.
'essentially' means to look at the middle letters.
'in' means one lot of letters goes inside another.
'place' becomes 'station' (station is a kind of place).
The central letters of 'fall' are 'al'.
'al' going into 'station' is 'SALTATION'.
Can you help me to learn more?
(Another definition for saltation that I've seen is " Abrupt variation".)
