We put the shout-out on social media and we were flooded with responses.

We gathered what we thought were the best responses and the toughest words – from beginner level to extremely advanced. And a warning: Number ten is really hard.

Without further ado:

1. Mille-feuille

Fancy some custard slice? Well not if it’s mille-feuille, says Facebook fan Deborah Adams Kutch. “It’s physically impossible for me to pronounce correctly,” she says. 

“I have had more than one session with several obliging patisserie ladies trying to teach me, much to their hilarity.”

2. Brouilly

Another item that’s top of the unpronounceable list is “Brouilly“, a type of red wine from the area bearing the same name in the Beaujolais region. Lynn Segal on Facebook says: “I don’t drink it anymore because I’ve been laughed at so many times! I can’t figure out how to say the B at the front of the mouth and the R at the back.”

3. Rouen

4. Bouilloire 

Tweeter Richard Milne says that “without a doubt” the hardest French word to pronounce for him is bouilloire (which means kettle).

“It’s got so many vowels/soft sounds that I sound like somebody is strangling me when I say it,” he says. 

On Facebook, Shelby Marcus Ocana says the toughest for her is the word “froid” (which means cold). And it sounds as if it’s that pesky rolled r in the middle that’s causing all the problems. 

“My kids always crack up when I say “J’ai froid” – they say I pronounce it like “foie” [which means liver].” She then has to endure inevitable series of jokes about foie gras from the little ones, she says.

8. Grenouille

This word, which means frog, popped up a lot. In fact, many readers sent in words ending in “ouille”. Jay Fogler on Facebook says the problem with the word grenouille is the complex rolling of the r and the combination of the ou i and ll. Enough to drive you hopping mad!

9. L’eau

Catherine Gheribi on Facebook says it’s one of the simplest, yet most important words of all that she gets tangled up on.

“When I say l’eau – no one ever understands what I mean,” she says. 

In fact, she says that even when a waiter asks whether she would like water or wine and she responds “L’eau s’il vous plait” – they still look at her blankly. 

“I want to shout ‘I DIDN’T SAY DU VIN DID I? – SO IT MUST BE THE OTHER ONE’!!. She says that she’s learned to order ‘une carafe’ now.

10. Serrurerie

Brace yourself: The hardest French word to pronounce is the word for locksmith – “serrurerie“. It was the most commonly repeated response. Blogger Polly-Vous Francais even sent us an entire blog entry about the word. 

She says: “Forget it. It is not happening. It requires too many mellifluous, throaty French r’s in too short a time frame (…) I find that I’ve barely recuperated from rolling out the first r when the next r and the next r need to come flying out of my tonsils.”
