What Does qu’est-ce que c’est Mean?
To a non-native speaker, qu’est-ce que c’est can be a source of frustration.
We can translate it as, “What is it”—and that captures the basic meaning.
But what’s with all the extra words?
Anatomy of an idiomatic expression
Let’s break this down a bit.
First of all, the initial qu’ of qu’est-ce: It’s short for que, meaning “that.”
Que ends in a silent e. When it’s placed next to est-ce, it loses its silent e in a process called elision. (Don’t feel bad, though. Que may lose its e, but it gets a snazzy new apostrophe to put in its place.)
So, est-ce. Just what is this vowel-stealing component of qu’est-ce que c’est?
Est simply means “is.” It’s just the present-tense, third person conjugation of être (to be).
And the little tag-on, -ce? It merely means “this.” Or “that.” It’s barely noticeable. It’s barely even uttered. (Just add a very slight hissing sound after you say est, before you pronounce que.) Technically, ce is a demonstrative adjective. It usually goes in front of a noun, to indicate “this (one)” or “that (one).”
Put together, est-ce literally means “is this”—or “is that.”
So far, we have qu’est-ce—“what is this.”
Next up, another que (that). This que doesn’t lose its –e like the last one did. It’s used as a conjunction to introduce the next part of the phrase—c’est (it is).
And here’s where things get really weird, because we now have the full phrase: qu’est que c’est. A phrase that can be literally translated as, “What is this that it is?”
Qu’est-ce que c’est versus est-ce que
All this talk of qu’est-ce que c’est may bring to mind the heart of this expression: est-ce que.
Est-ce que (is it that) gets a lot of mileage in French.
You may have been taught est-ce que as a way to ask questions:
- Est-ce que Paul est ici ? (Is Paul here?)
- Est-ce qu’il connaît Sandrine ? (Does he know Sandrine?)
- Est-ce que l’avion vient d’arriver ? (Did the plane just arrive?)
- Est-ce qu’on va arrêter de poser toutes ces questions ? (Will we stop asking all these questions?)
Qu’est-ce que c’est, like est-ce que, is an interrogative. Even though they share a core of words, they’re not interchangeable.
Est-ce que basically means “is,” or “does,” or “will,” depending on the context.
Qu’est-ce que c’est, on the other hand, asks “what.”
Shades of meaning
In more casual French, you’ll often hear, c’est quoi, ça ?—literally meaning, “it’s what, this/that?” (We’d say, “What’s this?” or “What’s that?” in English.)
Qu’est-ce que c’est is a bit more formal than c’est quoi, ça. However, it’s not always more polite.
Depending on the context and tone of voice used, qu’est-ce que c’est can be used to express a wide variety of emotions and shades of meaning.
