French Prepositions With Countries and Cities: The Rules That Actually Stick

The short answer: use 'en' before feminine countries and continents, 'au' before masculine countries, 'aux' before plural countries, and 'à' before cities. That covers about 90% of real usage. The other 10% involves a few irregular cases and some tricky masculine country names that trip up learners at every level from A2 onward.

Why This Rule Matters More Than It Seems

Getting this wrong is one of the most common errors French teachers flag on written exams, including the TCF and TEF Canada. A sentence like 'Je vis au France' marks you immediately as a beginner, even if the rest of your sentence is perfect. The good news is the rule has a clear logic once you understand that country gender follows the same noun-gender system you already know.

Step 1: Determine the Gender of the Country

Most French country names ending in -e are feminine. Most ending in any other letter are masculine. There are exceptions, but this pattern holds for the vast majority of countries you will actually use.

Notice Mexique. It ends in -e but is masculine. It is one of the most frequently tested exceptions. Cambodia (Cambodge) is the same: ends in -e, masculine, so 'au Cambodge'. Mozambique is another. Memorize these three and you will cover 95% of the exceptions you encounter in real life.

The Full Preposition Chart

That row about masculine countries starting with a vowel is important. 'Au Iran' would create a vowel clash, so French uses 'en' instead. This applies to Iran, Irak, Israël, Ouganda, and a handful of others. The rule is phonetic: avoid the hiatus.

Cities: Just Use À (Almost Always)

Cities do not have gender for this purpose. You always use 'à': à Paris, à Londres, à New York, à Dakar, à Québec. The only exception is a small set of cities whose names include a definite article, such as Le Havre or La Havane. For those, you contract normally: au Havre, à La Havane. This is rare and usually comes up only in reading comprehension, not conversation.

Talking About Origin: De, Du, Des

When you say where someone or something comes from, the pattern mirrors the prepositions above but uses 'de' and its contracted forms.

Common Mistakes at Each Level

• A1-A2: Writing 'au France' or 'en Canada' because learners have not yet internalized country gender.
• B1: Forgetting the vowel-sound rule and writing 'au Iran' instead of 'en Iran'.
• B2: Mishandling French regions, especially masculine ones that need 'dans le' rather than 'en'.
• C1: Using 'de' when the correct form is 'du' in complex noun phrases ('un produit de Japon' instead of 'du Japon').

A Quick Memorization Trick

Think of it in three questions. First: is it a city? Use 'à'. Second: is the country name plural? Use 'aux'. Third: is the country feminine (or masculine but starting with a vowel)? Use 'en'. Otherwise: use 'au'. Running through those three questions takes about two seconds once it becomes automatic.

Ville = à. Pluriel = aux. Féminin (ou voyelle) = en. Sinon = au.

If you are working through structured lessons at your level, you will see this pattern reinforced in context across reading and listening exercises, which is far more effective than reviewing a table once and hoping it sticks.

Why This Comes Up on TCF and TEF Canada

Immigration-related writing and speaking tasks often involve mentioning countries, cities of origin, and places of residence. Errors here appear in the writing production and oral expression sections. Examiners notice them because they are systematic, not random. If you are preparing for either exam, preposition accuracy with place names is a quick win. You can review what each exam section covers on the Fréquence Canada prep page.

FAQ

Do I use 'en' or 'au' for Canada?

Use 'au Canada'. Canada is masculine (ends in -a, not -e), so it takes 'au'. This surprises many learners because they assume all major immigration destinations follow one rule.

How do I know if a country is feminine or masculine in French?

The fastest shortcut: if the country name ends in -e, it is usually feminine (en France, en Chine, en Italie). If it ends in any other letter, it is usually masculine (au Japon, au Maroc, au Sénégal). The main exceptions to memorize are Mexique, Cambodge, and Mozambique, which end in -e but are masculine.

What preposition goes before a French region like Bretagne or Provence?

Feminine regions use 'en': en Bretagne, en Normandie, en Provence. Masculine regions use 'dans le': dans le Midi, dans le Périgord. If you are unsure of the gender, checking a dictionary for the article (la Bretagne vs le Périgord) gives you the answer immediately.

Is it 'à Québec' or 'au Québec'?

Both are correct but mean different things. 'À Québec' refers to Quebec City. 'Au Québec' refers to the province of Quebec. This distinction comes up constantly for anyone living in or moving to Canada, and mixing them up confuses native speakers.

Putting It Into Practice

Learning a rule is one thing. Retaining it under exam pressure or in a real conversation is another. The most reliable way to internalize preposition patterns is through repeated exposure in context: reading sentences that use them correctly, hearing them in audio, and being tested on them with feedback. If you want to check where you currently stand with grammar like this, the Fréquence level test places you at the right point so you are not reviewing things you already know.

Fréquence (frequence.academy) offers structured lessons from A1 through C1 that cover exactly this kind of grammar in context, not in isolation. The first three lessons are free and require no credit card.
