Irregular Verbs: Tener, Hacer, Ir

What Makes a Verb "Irregular"?

As you know, regular verbs follow a neat, predictable pattern: you take the stem and add a standard ending for -ar, -er, or -ir verbs. Irregular verbs, by contrast, break this pattern. Their stems might change, their endings might be unique, or both.

To start, let's watch a short video that defines this concept clearly.

The key takeaway is that for irregular verbs, simple pattern-matching isn't enough; we need to learn their specific forms. However, this isn't pure memorization. As you'll see, many irregularities follow patterns of their own, which is a much more efficient way to learn them.

1. The Verb tener – to have

Tener is one of the most versatile verbs in Spanish. It means "to have" in the sense of possession, but it's also used in dozens of essential idiomatic expressions.

The irregularity in tener is twofold:

1. The yo form is unique: tengo (a "yo-go" verb).
2. Other forms (except nosotros and vosotros) have a stem change: the e becomes ie.

This image clearly lays out the conjugations and some of the most common tener expressions you'll need for small talk.

Common Uses of Tener:

• Possession: Tengo una reserva en el hotel. (I have a reservation at the hotel.)
• Age: ¿Cuántos años tienes? (How old are you?) Tengo treinta años. (I am 30 years old.)
• Obligation (tener que + infinitive): Tenemos que ir a la ceremonia. (We have to go to the ceremony.)
• Physical States: Tengo hambre. (I'm hungry.), Tengo sed. (I'm thirsty.), Tengo frío/calor. (I'm cold/hot.)

A fantastic "how-to-learn" strategy is to recognize "verb offspring." Many irregular verbs form the basis for other, longer verbs that follow the exact same conjugation pattern. Tener is a great example.

So, if you know yo tengo, tú tienes, you automatically know yo mantengo, tú mantienes. This is the kind of systematic leverage you appreciate.

2. The Verb hacer – to do / to make

Hacer is another cornerstone verb, used for talking about actions, activities, and creation. Its irregularity is simpler than tener's because it only occurs in the first-person singular (yo) form.

Let's consult a resource that highlights this type of irregularity.

This "yo-go" pattern (hago, tengo, pongo, salgo) is a key pattern among irregular verbs. After the yo form, hacer conjugates like a regular -er verb.

Here is the full conjugation:

Example Sentences:

• ¿Qué haces? (What are you doing?) - A perfect conversation starter.
• Hago software para tecnología médica. (I make software for medical technology.)
• Mis amigos hacen una fiesta. (My friends are having a party / making a party.)

3. The Verb ir – to go

Ir is perhaps the most irregular verb in the present tense. Its conjugated forms look nothing like the infinitive. However, it's extremely short and follows a consistent, albeit unique, pattern. Because it's used so frequently, its forms become second nature with practice.

Here is the conjugation table.

The most powerful use of ir is to talk about the future, which is essential for making plans and small talk at the wedding. The structure is simple and incredibly useful:

ir (conjugated) + a + infinitive verb

This is the equivalent of "going to do something" in English.

Example Sentences:

• Voy a la boda en Colombia. (I am going to the wedding in Colombia.)
• ¿Vas a bailar más tarde? (Are you going to dance later?)
• Vamos a comer pronto. (We are going to eat soon.)

Practice and Application

Now, let's put it all together. Imagine you are at the wedding reception. Fill in the blanks with the correct form of tener, hacer, or ir.

Scenario: You are chatting with a new acquaintance.

New acquaintance: ¡Hola! ¿Qué tal? ¿Tú _____ (1. ir) a la ceremonia mañana?
(Hi! How's it going? Are you going to the ceremony tomorrow?)

You: Sí, claro. Y después, nosotros _____ (2. ir) a la recepción.
(Yes, of course. And afterwards, we are going to the reception.)

New acquaintance: ¡Genial! Oye, yo _____ (3. tener) un poco de sed. ¿Tú quieres algo de beber?
(Great! Hey, I'm a little thirsty. Do you want something to drink?)

You: Sí, por favor. Oye, una pregunta, ¿qué _____ (4. hacer) tú? ¿A qué te dedicas?
(Yes, please. Hey, a question, what do you do? What's your profession?)

New acquaintance: Soy fotógrafo. Yo _____ (5. hacer) las fotos para los novios hoy.
(I'm a photographer. I'm taking the photos for the bride and groom today.)

Conclusion

Fantastic work today. You've just added three of the most powerful and common verbs in Spanish to your toolkit. While they are "irregular," learning them systematically by recognizing patterns (yo-go verbs) and relationships ("verb offspring") is far more efficient than rote memorization.

Key Takeaways:

• Tener (to have): Irregular in the yo form (tengo) and has a stem change (e → ie). It's used for possession, age, and many key expressions.
• Hacer (to do/make): Primarily irregular in the yo form (hago). The other forms are regular.
• Ir (to go): Highly irregular (voy, vas, va...). Crucial for talking about movement and future plans using the ir + a + infinitive structure.

Preview of the Next Lesson:
We just saw how useful ir + a + infinitive is for talking about future actions. In the next lesson, we'll learn another structure for talking about what is happening right now. We will learn how to use the present progressive (estar + gerund) to describe ongoing actions, such as estoy hablando (I am talking) or estamos bailando (we are dancing). This will add another dynamic layer to your conversational abilities.
