/dʒæz/·noun·1913 in the San Francisco Bulletin (E.T. 'Scoop' Gleeson, sports column, March 6, 1913), referring to baseball energy; first applied to music by 1915 in Chicago, with the Original Dixieland Jass Band popularising the spelling 'jazz' by 1917·Established
Origin
Jazz emerged in 1910s American English from disputed origins — possibly West African, Creole French, or untraceable slang — then rode twentieth-century American cultural exports to become one of the most universally recognized loanwords on earth.
Definition
A music genre originating in early 20th-century New Orleans African-American communities, characterized by improvisation, syncopation, and swing rhythms, borrowed as a loanword into virtually every world language with minimal phonological adaptation due to its cultural prestige as an American export.
The Full Story
American English (debated African / Creole substrate)Early 20th century (1910s)well-attested
Theetymology of 'jazz' is one of the most contested in English. No single origin has been definitively established, and the word's journey is lateral rather than linear — emerging from overlapping oral cultures in the American South rather than a clean chain of borrowings. The leading hypotheses are: (1) West

When jazz reached China in the 1920s, translatorsfaced a dilemma: Mandarin has no 'j' + 'æ' + 'z' sequence. They settled on 爵士 (juéshì), borrowing characters that individually mean 'noble rank' and 'scholar.' Thephonetic approximation accidentally rebranded a music born in New
French 'jaser/gaser.' This Creole channel is geographically plausible given New Orleans as the cradle of the genre. (3) American slang of obscure origin, possibly from 'jasm' or 'gism' (meaning energy, vigor, spirit), attested in American English from the 1860s. The shift from 'jasm' to 'jazz' follows regular informal phonological reduction. (4) A proper-name origin from 'Jasbo' or 'Chas' (Charles), referring to specific musicians — though these are folk etymologies with weak evidence. The earliest documented uses of 'jazz' appear in San Francisco sports journalism in 1913, applied to baseball (meaning pep, energy), not music. By 1915 it was applied to the syncopated music emerging from New Orleans. The word likely travelled orally through African American communities in the South before entering print. True cognates do not exist — this is not an inherited Indo-European word but a cultural coinage with possible African substrate and French Creole reinforcement. The convergence of West African rhythmic vocabulary, French Creole oral culture, and American vernacular slang in New Orleans created the conditions for this word to crystallize. Key roots: jasi (Mandinka (West African): "to become abnormal, to act energetically"), jaser (Creole French / Old French: "to chatter, to make animated noise"), jasm (American English slang: "energy, vigor, spirit").
