pairwise, adverb


1. Pair, brace, couple, span, yoke are terms for groups of two. Pair is used of two things naturally or habitually associated in use, or necessary to each other to make a complete set: a pair of dice. It is used also of one thing composed of two similar and complementary parts: a pair of trousers. Brace is a hunter's term, used of a pair of dogs, ducks, etc., or a pair of pistols or slugs: a brace of partridges. In couple the idea of combination or interdependence has become greatly weakened; it may be used loosely for two of anything (a couple of apples), and even for more than two: I have to see a couple of people. Span is used of a matched pair of horses harnessed together side by side. Yoke applies to the two animals hitched together under a yoke for drawing and pulling: a yoke of oxen.


When used without a modifier, pairs is the only possible plural: Pairs of skaters glided over the ice. When modified by a number, pairs is the more common form, especially referring to persons: Six pairs of masked dancers led the procession. The unmarked plural pair is used mainly in reference to inanimate objects or nonhumans: He has three pair (or pairs) of loafers. Two pair (or pairs) of barn owls have nested on our property.
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.

[Middle English, from Old French paire, from Latin paria, equals, pl. of pār, a pair, from pār, equal; see perə-2 in Indo-European roots.]
Usage Note: The noun pair can be followed by a singular or plural verb. The singular is always used when pair denotes the set taken as a single entity: This pair of shoes is on sale. A plural verb is used when the members are considered as individuals: The pair are working more harmoniously now. After a number other than one, pair itself can be either singular or plural, but the plural is now more common: She bought six pairs (or pair) of stockings.

pair  (n.)
c.1290, "two of a kind, coupled in use," from O.Fr. paire, from L. paria "equals," neut. pl. of par (gen. paris) "a pair, counterpart, equal," noun use of par (adj.) "equal," of unknown origin, perhaps connected with *per-, PIE root meaning "to sell, buy" (on notion of "give equal value for"), which would connect it with L. pretium "price," Lith. perku "I buy," Gk. porne "prostitute," lit. "bought, purchased." Or from PIE *pere- "to grant, allot" (which would connect it with part and portion). The verb, "to mate" is first attested 1611 in Shakespeare ("Winter's Tale"); sense of "to make a pair by matching" is from 1613; these often are distinguished now by pair off (c.1803) for the former and pair up (1908) for the latter. Pair bond (v.) is first attested 1940, in ref. to birds mating.
