Other ways to say “I don’t know in French”

Similar to English, there are lots of other ways to say, “I don’t know” in French. Let’s have a look at some of those ways.

Je n’ai aucune idée

The phrase “Je n’ai aucune idée” means “I have no idea”, or “I haven’t the foggiest”. The word “aucun” means any. It takes an -e in this phrase because the word “idée” (idea) is feminine.

Je ne suis pas sûr(e)

“Je ne suis pas sûr(e)” means “I am not sure”. The word “sûr” translates to both sure and safe. Without the circumflex accent, “sur” translates to “on” or “on top of”. The “(e)” is used to indicate the feminine form.

Je n’en sais rien

“Je n’en sais rien” translates to “I haven’t got a clue”. A literal translation of “Je n’en sais rien” is “I know nothing about that”. In French slang the n’ is omitted to form: “J’en sais rien”.

Je n’en ai pas la moindre idée

“Je n’en ai pas la moindre idée” is yet another way of saying “I don’t know”. Translations include “I have no idea” and “I haven’t the foggiest”. A literal translation is “I do not have the least idea about that”.

The word “moindre” translates to “least”.

Qui sait!

“Qui sait!” is an interjection that translates to “Who knows!”. The usage is the exact same as in English. For example, “Où est Jacques? – Qui sait!” (Where is Jacques? – Who knows!).

Qu’est-ce que j’en sais ?

“Qu’est-ce que j’en sais ?” translates to both “Search me” and “What do I know”? A literal translation is: “What do I know about that”. Another translation include “beats me”.


The verb “ignorer” is a false cognate (word that looks the same in both language but has a different meaning). In French, “ignorer” means to know not know.

For example, “La police ignore encore la cause de l’incendie” (The police still don’t know the cause of the fire).
