What does the French words est-ce que mean in English?

"Est-ce que" in French is a way of asking a question. It directly translates to "Is it that", but in English, it's best understood as:

* "Do"

* "Is"

* "Are"

It's used to introduce a question, similar to how we use "Do" or "Is" in English.

Example:

* French: Est-ce que tu es fatigué?

* English: Are you tired?

Note: "Est-ce que" is often omitted in informal French, but it's still grammatically correct and often used in formal writing.
