Accent Grave vs Aigu: choisir le bon

The hardest accent decision in French is choosing between é (acute) and è (grave). They look almost the same on the page, they sit on the same letter, and English speakers often perceive them as the same sound — but they are two different vowels, and the choice between them is not arbitrary. Most of the time, you can predict which one to write from a single rule about the shape of the syllable. This page gives you that rule, the verbs that systematically alternate between é and è, and the small group of à/ù words where the grave is doing a completely different job.

The two sounds

Before we talk about spelling, hear the two sounds.

• é = /e/ — a tight, closed vowel. The mouth is small, the tongue is high. English approximation: the ay in say, without the final y glide. Examples: été, café, parler, école.
• è = /ɛ/ — a relaxed, open vowel. The mouth is wider, the tongue lower. English approximation: the e in bet. Examples: mère, frère, très, après.

Here you have both accents in one sentence: é in préfère's first syllable (open syllable: pré-), and è in the stressed syllables of mère, préfère, and très (all closed by a consonant).

In modern French — especially in the north and in standard educated speech — ê is pronounced the same as è: open /ɛ/. So tête, bête, and fête rhyme exactly, and acoustically they match cette and mette. The e with circumflex is a historical-spelling matter (the words used to be teste, beste, feste); the sound is the same as è.

The syllable rule

This is the workhorse rule that handles 90% of cases. It comes from the way French syllables are built.

Inside a word, you write é in an open syllable and è in a closed syllable — when the next syllable contains a "real" vowel.

Let me unpack:

• An open syllable ends in a vowel (consonant-vowel: pré, té).
• A closed syllable ends in a consonant (consonant-vowel-consonant: mè-re — the r closes the first syllable phonetically; père is one syllable but the consonant after è counts as the closer).

So:

• ré-pé-ter: each /e/ syllable ends in the vowel itself → é, é, then -ter with a normal e.
• mère: the vowel is followed by -re whose e is silent — the vowel sits in a closed syllable → è.
• père, frère, très, après, succès: same pattern. The r (or another consonant) closes the syllable.

père (è — closed syllable), célébré (é, é, é — three open syllables in a row), anniversaire (no accent — the e sits before a doubled or stressed consonant cluster).

The rule predicts both how to spell and how to pronounce. If you encounter an unfamiliar word with é, you should expect /e/. If you encounter it with è, expect /ɛ/.

Verbs that flip: -é_er and -e_er

The syllable rule shows up most spectacularly in verbs whose stem ends in é or e followed by a consonant. As the endings change, the syllable structure changes, and so does the accent.

Type 1: -é_er verbs (préférer, espérer, célébrer, répéter, exagérer)

These have é in the infinitive. When the verb ending starts with a silent e (the present singular endings -e, -es, -e and the third-plural -ent), the é changes to è because the syllable becomes closed.

This is not an arbitrary list of exceptions — it's the syllable rule applied across a paradigm. The accent always tracks the pronunciation.

Note on the 1990 reform: the reform extended this pattern further, allowing je céderai (futur, future) → je cèderai, je céderais (conditionnel) → je cèderais. Both spellings are now correct. The old norm kept é in futur and conditionnel because the next syllable was felt to be open; the reform standardizes toward è to match the pronunciation.

Type 2: -e_er verbs (acheter, lever, mener, peser, semer)

These have a plain e (no accent) in the infinitive. When the next syllable becomes silent, that e takes a grave accent to mark the now-open /ɛ/.

A second pattern exists for verbs in -eler and -eter (appeler, jeter): most of these double the consonant instead of taking a grave (j'appelle, je jette). A small group goes the acheter way (acheter, geler, peler, modeler). For the full breakdown, see verbs/fundamentals/spelling-changes-overview.

When è and é aren't about sound

For two letters, the grave is doing something completely different — it's marking a word distinction with no pronunciation consequence.

à vs a

• a = the verb avoir in the third person singular ("has"): il a, elle a, on a.
• à = the preposition meaning "to, at, in" — and a few derived uses (à toi, à demain, à Paris).

The grave does not change the pronunciation — both are /a/. It is a pure graphic distinction, like the apostrophe in English it's vs its.

Three different a-shapes in one sentence: a (has), à donner (to give), à Marie (to Marie). The accent is the only way to tell which is which on paper.

où vs ou

• ou = the conjunction "or": thé ou café.
• où = "where" (relative or interrogative): où vas-tu ?, la ville où je suis né.

Same sound /u/, same letter, different word. The accent disambiguates.

ù: a letter with one job

The grave on u exists in modern French in exactly one common word: où. There is no other word in the standard dictionary that uses ù. (A few proper names from older or dialectal sources do — but no everyday vocabulary.) If you type ù in any other context, it is almost certainly a mistake.

Source-language comparison

English speakers tend to perceive é and è as the same sound, because English doesn't make this distinction phonemically. American English has /e/ in bait (close to French é) and /ɛ/ in bet (close to è), but they never contrast in the same position the way French does. As a result, English speakers writing French make two characteristic errors:

1. Choosing the wrong accent because they can't hear the difference. Spelling préfere instead of préfère, or celebré instead of célébré. The syllable rule is the cure: don't try to hear it, look at the syllable structure.
2. Skipping accents on à and ù altogether because "they don't change the sound, so they're probably optional." They are not — they are obligatory word distinctions. Writing Je vais a Paris is the French equivalent of writing Im going to Paris without the apostrophe in I'm.

Common Mistakes

Key takeaways

• é is the closed /e/ sound; è is the open /ɛ/ sound. They are different vowels.
• The syllable rule: inside a word, write é in an open syllable, è in a closed syllable. Ré-pé-ter (three open syllables → all é) vs mère, père, frère (closed → è).
• Verbs in -é_er (préférer, espérer) flip é → è before silent endings: je préfère, ils préfèrent, but nous préférons.
• Verbs in -e_er (acheter, lever) take a grave on the stem before silent endings: j'achète, but nous achetons.
• The grave on à and ù is a pure spelling distinction — it does not change the sound. à (to) vs a (has), où (where) vs ou (or).
• ù appears in essentially one word: où.
• The 1990 reform has extended the é → è pattern into futur and conditionnel forms of -é_er verbs (je cèderai alongside je céderai).
