'on the edge' is the wordplay.
'on' becomes 're' ('on' can be mean 'with reference to').
'the edge' becomes 'side' (edge can mean the side of something).
're'+'side'='RESIDE'
(Other definitions for reside that I've seen before include "Lodge" , "Hang out with" , "Live (at an address)" , "Desire (anag) - to live" , "Dwell - settle" .)
