Oxford’s 2023 Word of the Year Is … ‘Rizz’ -    

Sorry, Swifties. The Gen Z slang term — derived from “charisma” — went viral this year after the actor Tom Holland claimed to have none.

It’s official. Oxford University Press, the world’s second-oldest academic press and the publisher of the Oxford English Dictionary, has rizz.
