gridlock

Etymology

It is formed from English grid + lock,^{[2][3][4][5][6]} the grid being a network of intersecting city streets.^[5][7] Merriam-Webster Unabridged and Webster's Third take the second part as deadlock rather than lock alone.^[7][8] The OED reports that the word was apparently coined by two transport engineers of the New York traffic department, Roy Cottam and Sam Schwartz, and spread during the city's transit strike of early 1980;^[2] Schwartz later recalled that Cottam feared the grid of streets in the Theater District would "lock up", and that they simply joined grid and lock.^[2][9] Barry Popik notes, however, that Schwartz told William Safire in April 1980 that he had first heard the term around the office in 1971, so he did not coin it himself.^[9]

Earliest recorded meaning

Severe congestion in which queues of vehicles block a whole network of intersecting streets, so that traffic in every direction stops: 1980, in a contingency plan for the New York transit strike.^[2][7] Popik quotes the New York Times of 3 April 1980, which called it the dreaded condition that traffic engineers name "grid lock".^[9] Etymonline also dates the noun to 1980.^[3]

Semantic evolution

The word was American at first.^[5][4][6] Within a year it was used figuratively, from 1981 in Paul Theroux's The Mosquito Coast, for a situation, often a political one, in which no progress can be made.^[2][4] From 1983 it was also used of the breakdown of any process or system through overloading, and as an adjective.^[2] The verb, to cause a gridlock in or bring to a standstill, followed in 1982,^[2] though Etymonline dates it to 1987.^[3] In American politics legislative gridlock came to mean the blocking of legislation when the two parties divide power, and by 1991–1993 some commentators claimed that "gridlock is good" for the country.^[10]
