Questions & Answers about Desmunta la roda.

What form is desmunta here?

Here desmunta is the informal singular imperative of desmuntar, used when telling one person what to do.

So the full idea is:

• (Tu) desmunta la roda. = command to one person

A useful detail: this same form can also match the 3rd person singular present (he/she dismantles, you formal dismantle), but in a short standalone sentence like this, it is naturally understood as a command.

What is the infinitive, and how is desmunta built from it?

The infinitive is desmuntar.

To form the tu imperative for most regular -ar verbs, Catalan usually uses the same form as the 3rd person singular present indicative:

• desmuntar → desmunta
• parlar → parla
• tancar → tanca

So:

• desmunta = take apart / remove / dismantle!

Why is there no word for you in the sentence?

Catalan often omits subject pronouns when they are understood from the verb form. This is very common.

So instead of saying:

• Tu desmunta la roda

Catalan normally just says:

• Desmunta la roda

The verb already tells you this is addressed to tu in command form, so tu is unnecessary unless you want emphasis.
