two things insisting they're better together, and annoyingly often right.
means A pair is a set of two things that go together, either as a matched couple or as a single object made of two joined parts.
from From Old French 'paire,' from Latin 'paria' — the neuter plural of 'par,' meaning 'equal' (the same 'par' you reach in golf and dip below at par). So at its root, a pair is two things claiming to be equals, well-matched and meant for each other.
