Usage note

3, 21. Black, colored, and Negro —words that describe or name the dark-skinned peoples of sub-Saharan Africa and their descendants—have had a complex social history in the United States. A term that was once acceptable may now be offensive, and one that was once offensive may now be acceptable. Colored, for example, first used in colonial North America, was an appropriate referential term until the 1920s, when it was supplanted by Negro. Now colored is perceived not only as old-fashioned but offensive. It survives primarily in the name of the National Association for the Advancement of Colored People (NAACP), an organization formed when the word was not considered derogatory. Describing someone as “a person of color,” however, is not offensive. That term, an inclusive one that can refer to anyone who is not white, is frequently used by members of the African American community.
Negro remained the overwhelming term of choice until the mid-1960s. That decade saw a burgeoning civil-rights movement, which furthered a sense that Negro was contaminated by its long association with discrimination as well as its closeness to the disparaging and deeply offensive n-word. The emergence of the black power movement fostered the emergence of black as a primary descriptive term, as in “black pride.” By the mid-1970s black had become common within and outside the black community. But Negro has not entirely disappeared. It remains in the names of such organizations as the United Negro College Fund, people still refer to Negro spirituals, and some older people of color continue to identify with the term they have known since childhood. Negro then, while not offensive in established or historical contexts, is now looked upon in contemporary speech and writing as not only antiquated but highly likely to offend.
Black remains perhaps the single most widely used term today. It has outlived the briefly popular Afro-American and, when used as an adjective, is unlikely to cause negative reactions. As a noun, however, when referring to African Americans, it does often offend—perhaps because references to “the blacks” or “a black” lead easily to misguided generalizations. But note the newer term. The 1990s saw black leaders like Jesse Jackson promote African American, which he said had “cultural integrity,” in that it refers to ethnic origins rather than to skin color. While African American has not replaced black in common parlance, it works both as a noun and as an adjective.
This shifting from term to term has not been smooth or linear, and periods of change like the late 1960s were often marked by confusion as to which term was appropriate. The 1967 groundbreaking film Guess Who's Coming to Dinner, about a young interracial couple hoping that both sets of parents will accept their plans to marry, reflects the abundance of terminological choices available at the time. Various characters talk of a “colored girl,” a “colored man,” a “Negro,” and “black people.” Even the n-word appears once, used disparagingly by one black character to another. African American had not yet made it into the mix.

Word Origin and History for black out

black

adj.

Old English blæc "dark," from Proto-Germanic *blakaz "burned" (cf. Old Norse blakkr "dark," Old High German blah "black," Swedish bläck "ink," Dutch blaken "to burn"), from PIE *bhleg- "to burn, gleam, shine, flash" (cf. Greek phlegein "to burn, scorch," Latin flagrare "to blaze, glow, burn"), from root *bhel- (1) "to shine, flash, burn;" see bleach (v.).

The same root produced Old English blac "bright, shining, glittering, pale;" the connecting notions being, perhaps, "fire" (bright) and "burned" (dark). The usual Old English word for "black" was sweart (see swart). According to OED: "In ME. it is often doubtful whether blac, blak, blake, means 'black, dark,' or 'pale, colourless, wan, livid.' " Used of dark-skinned people in Old English.

Of coffee, first attested 1796. Meaning "fierce, terrible, wicked" is late 14c. The color of sin and sorrow since at least c.1300; sense of "with dark purposes, malignant" emerged 1580s (e.g. black magic). Black face in reference to a performance style originated in U.S., is from 1868. Black flag, flown (especially by pirates) as a signal of "no mercy," from 1590s. Black dog "melancholy" attested from 1826. Black belt is from 1875 in reference to districts of the U.S. South with heaviest African population; 1870 with reference to fertility of soil; 1913 in judo sense. Black power is from 1966, associated with Stokely Carmichael.

black

v.

c.1200, "to become black;" early 14c., "to make black, darken;" from black (adj.). Related: Blacked; blacking.

black

n.

Old English blæc "the color black," also "ink," from noun use of black (adj.). From late 14c. as "dark spot in the pupil of the eye." The meaning "black person, African" is from 1620s (perhaps late 13c., and blackamoor is from 1540s). To be in the black (1922) is from the accounting practice of recording credits and balances in black ink.

For years it has been a common practice to use red ink instead of black in showing a loss or deficit on corporate books, but not until the heavy losses of 1921 did the contrast in colors come to have a widely understood meaning. ["Saturday Evening Post," July 22, 1922]

Idioms and Phrases with black out

black out

1

Obliterate with black, as in crossing out words on a page or print on a screen. For example, They have blacked out all the obscene words in the subtitles to make this movie suitable for youngsters. This usage may be derived from an earlier meaning, “to stain or defame,” which dates from the 15th century (and probably alludes to “blackening” a person's reputation). [Mid-1800s]

2

Extinguish all lights. For example, The whole town was asleep, as blacked out as London during the war. In the early 1900s this expression alluded to the lights in a theater, but from about 1940 on it meant darkening an entire city to hide it from enemy bombers.

3

Lose consciousness, faint; also, experience a temporary loss of memory. For example, I couldn't remember a single note of the music; I blacked out completely, or The accused man claims he blacked out after his first drink. This usage is thought to have originated with pilots, who sometimes fainted briefly when pulling out of a power dive. It soon was transferred to other losses of consciousness or memory. [c. 1940]
