Is able to be an equal partner in a dance (3)
I believe the answer is:
can
'is able to' is the definition.
(I've seen this before)
'an equal partner in a dance' is the wordplay.
I cannot really see how this works, but
'an' could be 'a' and 'a' is present in the answer.
'partner' could be 'n' and 'n' is located in the answer.
A single letter 'c' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'be' acts as a link.
Can you help me to learn more?
(Other definitions for can that I've seen before include "Preserve fruit" , "Metallic container" , "Vessel" , "May" , "has power" .)
