What is veux in the past tense?

Here's how it works:

* "Vouloir" is the infinitive verb meaning "to want."

* "Veux" is the first person singular present tense form of "vouloir" (meaning "I want").

* "Voulais" is the first person singular imperfect tense form of "vouloir" (meaning "I wanted").

So, if you want to say "I wanted" in French, you would use "voulais".
