Preparamos dos tacos.

Spanish often leaves out subject pronouns because the verb ending already tells you who is doing the action.

• preparamos = we prepare or we prepared
• so nosotros is not necessary

You could say Nosotros preparamos dos tacos, but that usually adds emphasis, contrast, or clarity.

Preparamos can mean either:

• we prepare (present)
• we prepared (preterite / simple past)

This is a very common point of confusion for learners: for many -ar verbs, the nosotros form is identical in the present and the preterite.

So you need context to know which one it means.

For example:

• Cada viernes preparamos dos tacos. = Every Friday we prepare two tacos.
• Anoche preparamos dos tacos. = Last night we prepared two tacos.

It comes from the infinitive preparar (to prepare).

Breakdown:

• prepar- = verb stem
• -amos = ending for nosotros

So:

• preparar → preparamos

This is a regular -ar verb, so it follows the normal pattern.

Because Spanish nouns must agree with the number.

• un taco = one taco
• dos tacos = two tacos

Since taco ends in a vowel, you usually make it plural by adding -s:

• taco → tacos

The number dos does not change.

After an exact number, Spanish normally just uses:

• number + noun

So:

• dos tacos = two tacos

You do not usually say unos dos tacos for this meaning.

Compare:

• dos tacos = two tacos
• los dos tacos = the two tacos (specific tacos already known)
• unos tacos = some tacos (not specifically two)

No. The personal a is mainly used before a specific human direct object.

Examples:

• Veo a María.
• Ayudamos a nuestro profesor.

But tacos are things, not people, so there is no personal a:

• Preparamos dos tacos.

Tacos is a masculine plural noun.

Its singular form is:

• el taco

Its plural form is:

• los tacos

So if you use an article, it would be masculine:

• un taco
• dos tacos
• los tacos

Yes, that is grammatically correct.

But in normal Spanish, especially in simple sentences, the subject pronoun is often omitted because it is already clear from the verb.

So the more natural default is usually:

• Preparamos dos tacos.

You might include nosotros if you want emphasis, for example:

• Nosotros preparamos dos tacos, pero ellos prepararon tres.

A simple guide is:

• preh-pah-RAH-mos

The stress falls on ra: prepaRAmos

A few pronunciation notes:

• Spanish vowels are usually short and clear: e, a, o
• the r in preparamos is a single r, not a strong rr
• tacos is pronounced roughly TAH-kos

So the full sentence sounds approximately like:

• preh-pah-RAH-mos dos TAH-kos

Not always. Taco can have different meanings depending on the country and context.

In many contexts, especially if the meaning has already been given, tacos will mean the food. But in Spain, taco can also refer to a swear word or coarse language in some contexts.

So the sentence must be interpreted through context. Here, since the meaning is already shown to the learner, you should use that intended meaning.
