In the English language, the word nigger is an ethnic slur typically directed at black people, especially African Americans.The word originated in the 18th century as an adaptation of the Spanish word negro, a descendant of the Latin adjective niger, which means "black".It was used derogatorily, and by the mid-20th century, particularly in the United States, its usage by anyone other than a black person had come to be generally seen as pejorative, a racist insult. Accordingly, it began to disappear from general popular culture. Its inclusion in classic works of literature has sparked modern controversy.Because the term is considered extremely offensive, it is often referred to by the euphemism the N-word. However, it remains in use, particularly as the variant nigga, by African Americans among themselves. The spelling nigga reflects the pronunciation of nigger in non-rhotic dialects of English, particularly Black Vernacular English.

Etymology and history
The variants neger and negar derive from various European languages' words for 'black', including the Spanish and Portuguese word negro (black) and the now-pejorative French nègre, the 'i' entering the spelling "nigger" from those familiar with Latin. Etymologically, negro, noir, nègre, and nigger ultimately derive from nigrum, the stem of the Latin niger ('black'), pronounced [ˈniɡer], with a trilled r. In every grammatical case, grammatical gender, and grammatical number besides nominative masculine singular, nigr- is followed by a case ending. In its original English-language usage, nigger (then spelled niger) was a word for a dark-skinned individual. The earliest known published use of the term dates from 1574, in a work alluding to "the Nigers of Aethiop, bearing witnes". According to the Oxford English Dictionary, the first derogatory usage of the term nigger was recorded two centuries later, in 1775.
