Conjugating the French Verb Intéresser

For instance, "I have interest" is "j'intéresse" and "we will be interested" is "nous intéresserons."

The Present Participle of Intéresser

Useful as an adjective, gerund, or noun as well as a verb, the present participle of intéresser is intéressant. This is formed by adding -ant to the verb stem and is the standard way to form the participle.

The Past Participle and Passé Composé

The past participle intéressé is required to form the past tense passé composé. To complete it, you must also conjugate the auxiliary verb avoir and use the subject pronoun. For example, "I was interested" is "j'ai intéressé" and "we were interested" becomes "nous avons intéressé."

More Simple Intéresser Conjugations to Know

Beyond those simple conjugations, there are a few more forms of intéresser that you may need at times. The subjunctive verb mood, for instance, implies that the verb's action is questionable and not guaranteed. Similarly, when the action is dependent on something, the conditional verb mood is useful.

If you read some French, it's likely that you will encounter the passé simple. Both it and the imperfect subjunctive are literary tenses and are good to know or, at least, be able to recognize.

Subject Subjunctive Conditional Passé Simple Imperfect Subjunctive
j' intéresse intéresserais intéressai intéressasse
tu intéresses intéresserais intéressas intéressasses
il intéresse intéresserait intéressa intéressât
nous intéressions intéresserions intéressâmes intéressassions
vous intéressiez intéresseriez intéressâtes intéressassiez
ils intéressent intéresseraient intéressèrent intéressassent

For short and often assertive commands and requests, use the imperative verb form. When doing so, skip the subject pronoun. Rather than sayin "tu intéresse," you can simplify it to "intéresse."

(tu) intéresse
(nous) intéressons
