Most French writing errors fall into the same five categories — a pattern that becomes clear once you know what to look for. Identifying which of these mistakes appears most often in your own writing is the fastest way to improve your accuracy, whether you are preparing for TCF, DELF, or writing French for work or study.
Mistake 1: Confusing a and à
This is the single most common error in French writing at every level. A (without accent) is the third-person singular present of avoir: Elle a un chien. À (with accent) is the preposition meaning to, at, or in: Je vais à Paris. They sound identical — the accent only matters in writing.
Wrong: Elle va a l'école a pied. Correct: Elle va à l'école à pied.
The test: replace the word with avait. If the sentence still makes sense, it is the verb a. If not, it is the preposition à and needs the accent.
Mistake 2: Missing or Wrong Accent Marks
French accents are not optional — they change both the pronunciation and the meaning of words. Ou means "or"; où means "where." A is a verb; à is a preposition. Omitting accents in handwriting is often penalised, and omitting them in typed work signals a non-native writer to any French reader.
The accents that cause most problems:
When typing French, use a dedicated tool with one-click accent insertion rather than trying to remember keyboard shortcuts mid-sentence. The French Writing Editor puts every accented character one click away — no switching input method, no interruption to your writing flow.
Mistake 3: Wrong Noun Gender
French noun gender affects the article, every adjective that modifies the noun, and pronoun reference. Getting the gender wrong in one word can create a chain of agreement errors across an entire sentence. The most dangerous traps are nouns that contradict their suffix: le problème (not la problème), la fleur (not le fleur), le musée (not la musée).
Wrong: C'est un grande problème. Correct: C'est un grand problème. Always learn a new noun with its article — le problème, la fleur — never as a bare word. When you are unsure during practice, verify immediately rather than guessing. The French Gender Checker returns the correct article and plural for any noun in a single lookup.
Mistake 4: Translating Directly From English
English and French word order differs significantly, especially for adverb placement, reflexive verbs, and expressions with avoir vs être. Direct translation produces sentences that are grammatically wrong in French even when the vocabulary is correct.
Mistake 5: Choosing the Wrong Past Tense
The passé composé and imparfait are not interchangeable. The passé composé narrates completed events: Il a téléphoné hier. The imparfait describes past states, habits, and ongoing background conditions: Il téléphonait chaque soir. Mixing them randomly is one of the clearest signals to an examiner that the writer is at A2 rather than B1.
The test: ask whether the past action is a completed event (specific, bounded in time) or a state and habit (ongoing, no clear end point). Completed event → passé composé. State or habit → imparfait. Use the French Verb Conjugator to check the passé composé forms of irregular verbs — the past participle is where most errors occur.
Identifying your personal pattern is more effective than trying to improve everything at once. After your next writing practice session, read back your response and look only for these five categories of error. Note which appears most often — and focus your study there first.
