cou·ple·a·ble, adjective

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.

[Middle English, from Old French, from Latin cōpula, bond, pair.]

Usage Note: When used to refer to two people who function socially as a unit, as in a married couple, the word couple may take either a singular or a plural verb, depending on whether the members are considered individually or collectively: The couple were married last week. Only one couple was left on the dance floor. When a pronoun follows, they and their are more common than it and its: The couple decided to spend their (less commonly its) vacation in Florida. Using a singular verb and a plural pronoun, as in The couple wants their children to go to college, is widely considered to be incorrect. Care should be taken that the verb and pronoun agree in number: The couple want their children to go to college. · Although the phrase a couple of has been well established in English since before the Renaissance, modern critics have sometimes maintained that a couple of is too inexact to be appropriate in formal writing. But the inexactitude of a couple of may serve a useful purpose, suggesting that the writer is indifferent to the precise number of items involved. Thus the sentence She lives only a couple of miles away implies not only that the distance is short but that its exact measure is unimportant. This usage should be considered unobjectionable on all levels of style. · The of in the phrase a couple of is often dropped in speech, but this omission is usually considered a mistake, especially in formal contexts. Three-fourths of the Usage Panel finds the sentence I read a couple books over vacation to be unacceptable; however, another 20% of the Panel finds the sentence to be acceptable in informal speech and writing.

coupling programming, hardware
The degree to which components depend on one another. There are two types of coupling, "tight" and "loose". Loose coupling is desirable for good software engineering but tight coupling may be necessary for maximum performance. Coupling is increased when the data exchanged between components becomes larger or more complex.
