Compare pair and couple, which both take a before and of after, and have the meaning "a group of two.'' pair is used when the two items mentioned next come as a set, with one not usually used without the other: a pair of socks, a pair of gloves, or when there is one item that has two parts, as in a pair of shorts, a pair of scissors. couple is used for things of the same kind that happen to be two in number: a couple of books, a couple of chairs. Only couple has the sense of "a few, several,'' as in a couple of miles away. couple therefore can mean "two (or more)''; pair will almost always mean "two (or less).''

The phrase a couple of has been in standard use for centuries, especially with measurements of time and distance and in referring to amounts of money:They walked a couple of miles in silence.Repairs will probably cost a couple of hundred dollars.The phrase is used in all but the most formal speech and writing. The shortened phrase a couple, without of (The gas station is a couple miles from here), is an Americanism of recent development that occurs chiefly in informal speech or representations of speech. Without a following noun, the phrase is highly informal:Jack shouldn't drive.I think he's had a couple.(Here the noun drinks is omitted.)In referring to two people, couple, like many collective nouns, may take either a singular or a plural verb. Most commonly, it is construed as a plural:The couple were traveling to Texas.See also collective noun.
