##### Usage notes

The usual plural of pair is pairs. This is a recent innovation; the plural pair was formerly predominant and may be found in older texts like "A Key to Joyce's Arithmetic" (compare Middle English paire, plural paire). That is, a native English speaker, back in the early 19th century, would say 20 pair of shoes, as opposed to today's 20 pairs of shoes. In colloquial or dialectal speech, forms such as 20 pair may still be found; because of their relegation to informal speech, they are now sometimes proscribed.
