Usage notesEdit

In recent North American English nonplussed has acquired the alternative meaning of "unimpressed".[1] In 1999, this was considered a neologism, ostensibly from "not plussed", although "plussed" by itself is not a recognized English word. The "unimpressed" meaning is proscribed as nonstandard by at least one authoritative source.[3]
