Ruling that binds you and me together? (13)
I believe the answer is:
pronouncement
'ruling that binds' is the definition.
'pronouncement' can be an answer for 'ruling' (thesaurus). I'm unsure of the remainder of the definition.
'you and me together?' is the wordplay.
'you' becomes 'pronoun' ('you' is a pronoun).
'and' is a charade indicator (letters next to each other).
'me together?' becomes 'cement' (I can't explain this - if you can you should give a lot more credence to this answer).
'pronoun'+'cement'='PRONOUNCEMENT'
Can you help me to learn more?
(Other definitions for pronouncement that I've seen before include "assertion" , "An authoritative declaration" , "official statement" , "Official declaration" , "formal statement" .)
