The Spanish Gerund Explained: Mastering -ando and -iendo

You’re walking through a beautiful plaza in a Spanish-speaking country. You overhear snippets of conversation: "Estoy buscando la catedral," "Los niños están comiendo helado," "Estamos aprendiendo mucho."

You notice a pattern: those -ando and -iendo endings keep popping up. What do they mean?

You've just stumbled upon the Spanish gerund! And while its name might sound a little intimidating, it's one of the most useful and straightforward concepts you'll learn. It's the key to describing actions as they happen.

Over each action, subtly display the corresponding Spanish gerund form in a stylized font (caminando, comiendo, hablando). Focus on continuous, gentle movement.

Let's dive in and master the Spanish gerundiogerund.

What Exactly is a Spanish Gerund?

Think of the Spanish gerund as the equivalent of the "-ing" form in English.

  • Walking -> Caminando
  • Eating -> Comiendo
  • Living -> Viviendo

It’s a special verb form that expresses an ongoing, continuous action. It answers the question, "What is happening right now?"

How to Form the Gerund: The Easy Part!

Creating the gerund in Spanish is incredibly consistent. There are just two main rules based on the verb's infinitive ending (-ar, -er, or -ir). If you need a refresher on these base forms, check out our guide on regular -er and -ir verb conjugations.

1. For -AR Verbs

Simply drop the -ar ending from the infinitive and add -ando.

  • Hablar (to talk) → habl + andohablando (talking)
  • Caminar (to walk) → camin + andocaminando (walking)
  • Comprar (to buy) → compr + andocomprando (buying)

2. For -ER and -IR Verbs

For both -er and -ir verbs, drop the infinitive ending and add -iendo.

  • Comer (to eat) → com + iendocomiendo (eating)
  • Aprender (to learn) → aprend + iendoaprendiendo (learning)
  • Vivir (to live) → viv + iendoviviendo (living)

That's it for most verbs! Simple, right?

The Tricky Part: Irregular Gerunds

Of course, Spanish loves to keep us on our toes with a few irregulars. But don't worry, they follow predictable patterns.

1. Stem-Changing -IR Verbs

If an -ir verb has a stem change in the present tense (like e→i or o→u), it will have the same change in its gerund form.

  • Decir (to say) → diciendo
  • Pedir (to ask for) → pidiendo
  • Sentir (to feel) → sintiendo
  • Dormir (to sleep) → durmiendo
  • Morir (to die) → muriendo

2. "Y" Gerunds

When the stem of an -er or -ir verb ends in a vowel, the -iendo changes to -yendo to avoid an awkward three-vowel pile-up.

  • Leer (to read) → le + iendoleyendo (not leiendo)
  • Creer (to believe) → cre + iendocreyendo
  • Traer (to bring) → tra + iendotrayendo
  • Ir (to go) → yendo (This one is highly irregular, but very common!)

Pronunciation Tip

The "y" in "-yendo" sounds like the "y" in the English word "yes." This change makes the words flow much more smoothly off the tongue. Try saying "le-iendo" and then "le-yendo"—you'll feel the difference!

How to Use the Gerund: The Present Progressive

The most common use of the Spanish gerund is to form the present progressive tense. This tense is all about what's happening right now.

Formula: estar (conjugated) + gerund

(For a complete understanding of when to use this verb, check out our guide on Ser vs. Estar.)

Let's see it in action:

  • Yo estoy hablando. (I am talking.)
  • estás comiendo. (You are eating.)
  • Él está leyendo un libro. (He is reading a book.)
  • Nosotros estamos aprendiendo español. (We are learning Spanish.)
  • Ellos están durmiendo. (They are sleeping.)

This structure is your go-to for describing actions in progress.

Arrange the words to form a correct sentence:

música.
ella
escuchando
Está

Common Mistakes to Avoid

Important Grammar Alert!

In English, we can use the "-ing" form as a noun (e.g., "Swimming is my favorite hobby."). You cannot do this in Spanish. The Spanish gerund is only for actions, not for nouns.

To use a verb as a noun in Spanish, you must use the infinitive (-ar, -er, -ir). This is the same principle used when expressing preferences with verbs like gustar (e.g., Me gusta leer).

Incorrecto ❌Correcto ✅

Caminando es buen ejercicio.

Caminar es buen ejercicio.

Drag the handle to compare

  • Nadar es divertido. (Swimming is fun.)
  • Me gusta leer. (I like reading.)

Beyond the Present Progressive

While the present progressive is the most common use, you'll also see the gerund used with other verbs to add nuance:

  • Seguir + gerund (to keep on doing something)
    • Sigo estudiando español. (I keep on studying Spanish.)
  • Llevar + time + gerund (to have been doing something for a period of time)
    • Llevo dos horas esperando. (I have been waiting for two hours.)
  • Andar + gerund (to go around doing something)
    • Anda diciendo mentiras. (He's going around telling lies.)

These are more advanced, but it's great to recognize them when you see them!

Frequently Asked Questions

Can I use the Spanish gerund as a noun like in English?

No, this is a very common mistake for English speakers. In English, we say 'Swimming is fun'. In Spanish, you cannot say 'Nadando es divertido'. You must use the infinitive verb as the noun, so the correct sentence is 'Nadar es divertido'.

What's the difference between a gerund and a present participle in Spanish?

In Spanish, the -ando/-iendo form is called the 'gerundio'. It's primarily used to describe ongoing actions. The past participle (ending in -ado/-ido) is used to form perfect tenses and as an adjective. For example, 'estoy hablando' (I am speaking - gerund) vs. 'la puerta está cerrada' (the door is closed - participle as adjective).

Are there many irregular gerunds in Spanish?

Thankfully, not too many! The most common irregulars are stem-changing -ir verbs like 'pedir' (pidiendo) and 'dormir' (durmiendo), and verbs with vowel changes like 'leer' (leyendo) and 'ir' (yendo). Once you learn the main patterns, you'll be able to spot them easily.
