Wary about married man pursuing single for dance (6)
I believe the answer is:
shimmy
'dance' is the definition.
(shimmying is a kind of dancing)
'wary about married man pursuing single' is the wordplay.
I cannot really understand how this works, but
'married' could be 'm' and 'm' is found within the answer.
'man' could be 'hi' and 'hi' is found in the answer.
This may be the basis of clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for shimmy that I've seen before include "Ragtime dance - gracefully sway" , "Body-shaking dance" , "Shaking ragtime dance" , "US ragtime dance - glide effortlessly" , "Elegantly move" .)
