Questions & Answers about Vols iogurt? Sí, en vull un ara.
Vols is the 2nd person singular present form of voler (to want).
- jo vull = I want
- tu vols = you want
- ell/ella vol = he/she wants
So Vols iogurt? is addressing one person informally: Do you want yogurt?
If you were speaking to more than one person, or using the polite form, you would use voleu instead.
Catalan often drops subject pronouns when they are clear from the verb form.
Because vols already tells you the subject is tu, Catalan normally does not need to say tu.
So:
- Vols iogurt? = normal, natural
- Tu vols iogurt? = possible, but more emphatic, as in Do you want yogurt?
This is different from English, where the subject usually has to be stated.
