Perhaps we bond, providing definitive ruling (13)
I believe the answer is:
pronouncement
'definitive ruling' is the definition.
(eg a pronouncement from a judge)
'perhaps we bond' is the wordplay.
'perhaps we' becomes 'pronoun' ('we' is a pronoun).
'bond' becomes 'cement' (cement can mean to stick or bond).
'pronoun'+'cement'='PRONOUNCEMENT'
'providing' is the link.
(Other definitions for pronouncement that I've seen before include "formal statement" , "assertion" , "Official declaration" , "ordinance" , "Edict" .)
