Obesity is the state of being very fat in a way that is unhealthy — the noun that sits beside the adjective obese. You hear it in medicine, public-health news, and school biology: childhood obesity, obesity rates, the obesity epidemic (a common, slightly dramatic newspaper phrase). It names a condition, not a person: we say people living with obesity more often now, rather than calling someone “an obesity.” It is formal; friends do not usually each other with this word.
肥胖；肥胖症（醫療／公衛用語）
組成From French obésité, from Latin obēsitās, from obēsus “fat.” On the surface: obese + -ity (the suffix that makes a noun of a quality).
