French Gerund: How it is formed
The French gérondif links two actions performed by the same subject. It is formed very simply: en + the present participle (for example en mangeant, "while eating"). It is used constantly in speech and writing to express simultaneity, cause, manner, or condition. This guide from SPRACHCAFFE explains how to form it, when to use it, the most common set expressions, and gives you two exercises with answer keys.
How the gérondif is formed
The gérondif is en + present participle. To build it you first need the present participle.
To form the present participle, take the nous form of the verb in the present tense, remove the -ons ending, and add -ant. Using the nous form matters, because it captures spelling changes and irregular stems.
- jouer → nous jouons → jouant → en jouant = playing
- attendre → nous attendons → attendant → en attendant = waiting
Irregular and spelling-change forms
Three very common verbs have irregular present participles:
- être → étant → en étant = being
- avoir → ayant → en ayant = having
- savoir → sachant → en sachant = knowing
These are the only true exceptions. Some verbs merely look odd because they follow the nous form: croire gives croyant, since nous croyons has a "y".
A few verbs adjust their spelling for ease of pronunciation (euphonic reasons), exactly as they do in the nous form:
- Verbs in -ger keep the "e": manger → nous mangeons → en mangeant; bouger → en bougeant.
- Verbs in -cer take a cedilla: commencer → nous commençons → en commençant; remplacer → en remplaçant.
When to use the gérondif
Like the English "-ing," the gérondif connects actions, but note one key limit: it does not translate the present continuous. For "I am eating," French uses the present tense (je mange) or être en train de + infinitive (je suis en train de manger), never "je suis mangeant."
The gérondif is used to express:
Simultaneity (two actions at once, same subject): - Comme d'habitude, tu parles en mangeant. → As usual, you talk while eating. - Sophie a écrit une lettre en écoutant de la musique. → Sophie wrote a letter while listening to music.
For simultaneity you can often use pendant que ("while") instead: - En marchant, vous regardez le ciel. → While walking, you look at the sky. - Pendant que vous marchez, vous regardez le ciel. → While you walk, you look at the sky.
Cause or means (how or why something happens): - Ils sont tombés en courant. → They fell while running (because they were running). - Je paie mes factures en travaillant honnêtement. → I pay my bills by working honestly.
Condition (by doing X, Y follows): - Tu te sentiras mieux en prenant le médicament. → You will feel better by taking the medicine. - En te comportant bien en classe, tu obtiendras d'excellents résultats. → By behaving well in class, you will get excellent results.
