They have their points in ballet dancing (4)
I believe the answer is:
toes
'they' is the definition.
Both the definition and answer are plural nouns.
Maybe there's a link between them I don't understand?
'their points in ballet dancing' is the wordplay.
I cannot really see how this works, but
'points' could be 'es' (two compass points) and 'es' is present in the answer.
The remaining letters 'to' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'have' acts as a link.
Can you help me to learn more?
(Other definitions for toes that I've seen before include "Divisions of foot front" , "Foot digits" , "Lower digits" , "What Pobble lacked (Lear)" .)
