Pair find route to bilateral agreement, perhaps? (3-3)
I believe the answer is:
two-way
'bilateral agreement perhaps?' is the definition.
I can't tell whether this defines the answer.
'pair find route' is the wordplay.
'pair' becomes 'two' (a pair means two of something).
'find' means one lot of letters go next to another.
'route' becomes 'way' (way is a kind of route).
'two'+'way'='TWO-WAY'
'to' is the link.
Can you help me to learn more?
(Other definitions for two-way that I've seen before include "Involving reciprocation" , "Involving movement in either direction" .)
