Je Ne Sais Quoi
idiom / noun /ʒə nə seɪ kwɑː/ — An indefinable quality that makes something special
Definition
A quality or attribute that is difficult or impossible to describe or name — something that makes a person or thing particularly special, attractive, or interesting but defies articulation.
Beyond the definition
Je ne sais quoi is what you say when you know something is there but cannot grab it with language. It's the honest admission that not everything can be named — that some qualities exceed the vocabulary available for them.
Origin & history
French: 'I don't know what'. Ironically, this French phrase became the English expression for the inexpressible — a name for the nameless.
