Économiser in context

Dialogue 1: every day

Marie and Paul talk about what they do every day. Notice how économiser changes with the person, and how the passé composé appears when they talk about yesterday.

Marie: “Tu économises de l’argent chaque mois tous les jours ?” — “You save money every month.” Paul: “J'économise de l’argent chaque mois tous les jours.” — “I save money every month.” Marie: “Tu as économisé de l’argent chaque mois hier ?” — “You have saved money every month.” Paul: “J'ai économisé de l’argent chaque mois hier.” — “I have saved money every month.” Marie: “Nous économiserons de l’argent chaque mois demain ?” — “We will save money every month tomorrow.” Paul: “Nous économiserons de l’argent chaque mois demain.” — “We will save money every month tomorrow.”

Dialogue 2: making plans

Paul and Marie make plans for the weekend. The conditional appears for polite suggestions, and the imperative for a direct request.

Paul: “J'économiserais de l’argent chaque mois si je pouvais.” — “I would save money every month if I could.” Marie: “Tu économises de l’argent chaque mois souvent ?” — “You save money every month.” Paul: “J'économise de l’argent chaque mois souvent.” — “I save money every month.” Marie: “Économise de l’argent chaque mois !” — “Save money every month!” Paul: “Il faut que je économise de l’argent chaque mois.” — “It is important that I save money every month.” Marie: “Nous avons économisé de l’argent chaque mois hier.” — “We have saved money every month.”

Read both dialogues aloud, changing the person each time: économise becomes économises, économises becomes économise, and so on. That is the fastest way to fix the six present forms — économise*, économises, économise, économisons, économisez, *économisent — in memory.

Common mistakes with économiser

Mistake 1: Using the infinitive instead of a conjugated form

Wrong: “Je économiser de l’argent chaque mois.”

Right: “J'économise de l’argent chaque mois.”

The infinitive économiser never takes a subject. After je you need the conjugated present form économise.

Mistake 2: Confusing économiser with dépenser

Wrong: “J'économise trop d’argent en vacances.” (meant as “dépenser”)

Right: “J'économise de l’argent chaque mois.”

économiser means “to save (money)” and dépenser means “to spend (money)”. They appear in similar situations, but they are different actions — check the meaning before you choose the verb.

Mistake 3: Using être for the passé composé

Wrong: “Je suis économisé de l’argent chaque mois.”

Right: “J'ai économisé de l’argent chaque mois.”

With économiser the passé composé is formed with avoir: ai économisé.

Mistake 4: Using the indicative after a subjunctive trigger

Wrong: “Il faut que je économise de l’argent chaque mois.”

Right: “Il faut que je économise de l’argent chaque mois.”

After il faut que French needs the subjunctive: économise, not the indicative économise.

Mistake 5: Mixing up the persons

Wrong: “Tu économise de l’argent chaque mois.”

Right: “Tu économises de l’argent chaque mois.”

After tu you need économises, not the je form économise.
