Definition and pronunciation
jazz
Noun — a genre of music rooted in African American traditions, marked by swing, syncopation, and improvisation; also “excitement/pep” in informal use.
Verb — jazz up: to enliven or decorate; be jazzed: to be excited (AmE).
Adjectives — jazzy (flashy, lively); jazzed (excited).
Pronounced /dʒæz/.
Easy explanation
Jazz is first and foremost music—think improvisation, rich rhythms, and expressive solos. People also use jazz up to mean make something more lively. Phrases like and all that jazz mean “and other similar stuff.”
Part of speech and grammar
- Count/uncount noun: jazz; a jazz record; jazz standards; modern jazz.
- Verb (phrasal/causative): jazz up [something] → They jazzed up the layout.
- Adjectives: jazzy outfit; I’m jazzed about the trip.

Register and tone
Neutral to artistic for the music sense; upbeat or colloquial for the “pep/excitement” sense. Jazzy can be positive (“stylish, lively”) or mildly pejorative (“flashy”) depending on tone.
Connection to sexuality
Mostly no in modern English. Jazz is about music or liveliness. Historically, some etymologies trace jazz to older slang for energy/vim (jasm), possibly related to jism; if true, that’s an indirect and historical link, not a current sexual meaning. Contemporary phrases like jazz up are not sexual.
