Introduction to the verb catalyser
The English translation of the French verb catalyser is “to catalyze.” It is pronounced as “ka-ta-lee-zay” in its infinitive form.
The word “catalyser” comes from the Greek word “katalusis,” meaning “dissolution,” and the suffix “-er,” used to form verbs in French. It was first used in the scientific field, specifically in chemistry, to describe the process of increasing the rate of a chemical reaction through the use of a catalyst.
In everyday French, the verb “catalyser” is most often used in the Passé Composé (Present Perfect) tense to describe an action that has been completed in the past. It is conjugated as “avoir catalysé” for most subjects, except for “je” and “tu” which use “ai” and “as” respectively instead of “avoir.”
