Faint poles bordering court (5)
I believe the answer is:
swoon
'faint' is the definition.
(I know that faint can be written as swoon)
'poles bordering court' is the wordplay.
'poles' becomes 'SN' (North and South poles).
'bordering' means one lot of letters goes inside another.
'court' becomes 'woo' (both can mean to romance someone).
'sn' placed around 'woo' is 'SWOON'.
(Other definitions for swoon that I've seen before include "experience ecstasy" , "Pass out" , "Show ecstasy" , "Faint (with emotion)" , "Display of extreme emotion" .)
