At critical moment, energy in dancer’s toes (6)
I believe the answer is:
pointe
'at' is the definition.
Both the answer and definition are singular nouns.
Perhaps there's a link between them I don't understand?
'critical moment energy in dancer's toes' is the wordplay.
I cannot quite see how this works, but
'moment' could be 'point' (a point in time) and 'point' is located in the answer.
'energy' could be 'e' (physics symbol as in E=mc2) and 'e' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for pointe that I've seen before include "Tiptoe (ballet)" , "Ballet position" .)
