Origin of pair1
Pair signifying two individuals can take either a singular or plural verb, but it is usually followed by a plural verb and referred to by a plural pronoun: The guilty pair have not been seen since their escape.
In the sense “a set or combination of more than two objects forming a collective whole,” pair occurs chiefly in fixed phrases: a pair of beads; a pair of stairs. This use is now somewhat old-fashioned. See also collective noun, couple.
