tandis que

Whereas with Tandis Que

Level 3

Tandis que is a formal way to say 'whereas' or 'while'. It links two clauses to show a contrast between two people or things, or to show that two actions are happening simultaneously.

How It Works

Tandis que is a subordinating conjunction used in two main ways:

1. Contrast (Opposition): This is its most frequent use. It highlights the difference between two subjects or situations. It is usually preceded by a comma in this context.
Example: Marc aime le thé, tandis que Julie préfère le café. (Marc likes tea, whereas Julie prefers coffee.)

2. Simultaneity (Time): It can also mean 'while' in a temporal sense, though pendant que is more common for pure time. Using tandis que for time often adds a slight nuance of comparison between the two actions.

Key Rules:

  • Mood: It is always followed by the indicative mood (the normal present, past, or future). Never use the subjunctive.
  • Elision: The 'e' drops before a vowel or mute 'h', becoming tandis qu'.
  • Pronunciation: The final 's' is often silent (/tɑ̃.di/), but pronouncing it (/tɑ̃.dis/) is also correct and common in formal speech or specific regions.
  • Register: It is more formal than alors que and is frequently found in writing and journalism.

  1. Le chat dort sur le canapé tandis que le chien joue dans le jardin.

    The cat is sleeping on the sofa while the dog is playing in the garden.

    Word by Word: The cat sleeps on the sofa while that the dog plays in the garden.

    Here, 'tandis que' shows two parallel actions happening at the same time with a slight contrast between the animals' behaviors.

  2. Ma sœur est très sportive, tandis que je suis plutôt intellectuel.

    My sister is very athletic, whereas I am rather intellectual.

    Word by Word: My sister is very athletic, whereas that I am rather intellectual.

    This demonstrates the contrastive use, highlighting the difference between two people.

  3. Reposez-vous un peu tandis qu'il prépare le dîner.

    Rest a little while he prepares dinner.

    Word by Word: Rest yourself a little while that he prepares the dinner.

    Note the elision (tandis qu') before the vowel 'i' in 'il'.

  4. L'hiver est froid au nord, tandis qu'il est doux au sud.

    Winter is cold in the north, whereas it is mild in the south.

    Word by Word: The winter is cold at the north, whereas that it is mild at the south.

    A classic geographical comparison using 'tandis que' to balance two facts.

Common Mistakes

  • Using the subjunctive mood after 'tandis que'.

    Je travaille tandis qu'il soit en vacances.
    Je travaille tandis qu'il est en vacances.

    Even though it ends in 'que', 'tandis que' expresses a fact and therefore requires the indicative mood, not the subjunctive.

  • Using 'tandis que' directly before a noun.

    Tandis que le film, j'ai dormi.
    Pendant le film, j'ai dormi.

    'Tandis que' is a conjunction and must be followed by a full clause (subject + verb). To say 'during' before a noun, use 'pendant'.
