A friend once froze in a cooking class when the chef said, “Agregue la sal.” She knew agregar meant “to add,” but suddenly one nice, normal verb had turned into a formal command. Spanish does that sometimes. Rudely.

The good news is that agregar is mostly a regular -ar verb. The only part that tends to trip people up is a small spelling change: g → gu before e. Once you spot that pattern in forms like agregué, agregue, and agreguemos, the rest gets much easier.

What Agregar Means

Most of the time, agregar means “to add”. It can also mean “to add” in the sense of “to mention one more thing”.

Spanish Pattern	English Meaning	Example Sentence
agregar algo a algo	to add something to something	Voy a agregar azúcar al café. I’m going to add sugar to the coffee.
agregar a alguien	to add someone	Voy a agregar a Marta al grupo. I’m going to add Marta to the group.
agregar un comentario	to add a comment	Puedes agregar un comentario aquí. You can add a comment here.
agregar que…	to add that…	Quiero agregar que no fue mi idea. I want to add that it was not my idea.

Present Tense

In the present tense, agregar behaves like a normal -ar verb. Nice. Civilized. No drama yet.

Subject	Conjugation	English Meaning	Example Sentence
yo	agrego	I add	Yo agrego una nota al informe. I add a note to the report.
tú	agregas	you add	Tú agregas sal al caldo. You add salt to the broth.
él / ella / usted	agrega	he / she adds; you add	Ella agrega más detalles. She adds more details.
nosotros	agregamos	we add	Nosotros agregamos el total al final. We add the total at the end.
ellos / ellas / ustedes	agregan	they add; you all add	Ustedes agregan a los clientes al sistema. You all add the clients to the system.

Spain also uses vosotros agregáis, but in Mexican Spanish you can safely stick with ustedes agregan.

Preterite Tense

The preterite is where the spelling change shows up. The yo form becomes agregué, not agregé, because Spanish wants to keep that hard g sound.

Subject	Conjugation	English Meaning	Example Sentence
yo	agregué	I added	Ayer agregué tu nombre a la lista. Yesterday I added your name to the list.
tú	agregaste	you added	Tú agregaste demasiada azúcar. You added too much sugar.
él / ella / usted	agregó	he / she added; you added	El profesor agregó un ejemplo más. The teacher added one more example.
nosotros	agregamos	we added	Nosotros agregamos otra diapositiva. We added another slide.
ellos / ellas / ustedes	agregaron	they added; you all added	Ustedes agregaron la dirección correcta. You all added the correct address.

Important: agregamos can mean “we add” or “we added.” The sentence context tells you which one it is.

Imperfect, Future, And Conditional

These tenses are much calmer. No spelling trap in the imperfect, and the future and conditional are built from the full infinitive agregar.

Tense	Core Forms	English Meaning	Example Sentence
Imperfect	agregaba, agregabas, agregaba, agregábamos, agregaban	used to add / was adding	Cuando cocinaba con mi abuela, siempre agregaba canela. When I cooked with my grandmother, she always added cinnamon.
Future	agregaré, agregarás, agregará, agregaremos, agregarán	will add	Mañana agregaré los datos que faltan. Tomorrow I will add the missing data.
Conditional	agregaría, agregarías, agregaría, agregaríamos, agregarían	would add	Yo agregaría más ejemplos si hubiera tiempo. I would add more examples if there were time.

Present Subjunctive And Commands

The present subjunctive comes from the yo form agrego. Drop the -o, then add the subjunctive endings. Since those endings begin with e, the spelling shifts to gu.

Subject	Conjugation	English Meaning	Example Sentence
yo	agregue	that I add	Es posible que yo agregue otra nota. It’s possible that I add another note.
tú	agregues	that you add	Quiero que tú agregues más información. I want you to add more information.
él / ella / usted	agregue	that he / she / you add	Dudo que ella agregue algo nuevo. I doubt that she adds anything new.
nosotros	agreguemos	that we add	Es bueno que agreguemos un resumen. It’s good that we add a summary.
ellos / ellas / ustedes	agreguen	that they add / that you all add	Espero que ustedes agreguen la fecha. I hope you all add the date.

Those same subjunctive-style forms also power several commands. So once you learn them, you get two wins for the price of one. Miraculous.

Command Type	Spanish	English Meaning	Example Sentence
tú affirmative	agrega	add	Agrega tu correo aquí. Add your email here.
tú negative	no agregues	don’t add	No agregues más agua. Don’t add more water.
usted affirmative	agregue	add	Agregue su firma al final. Add your signature at the end.
nosotros affirmative	agreguemos	let’s add	Agreguemos una nota breve. Let’s add a short note.
ustedes affirmative	agreguen	add	Agreguen sus preguntas aquí. Add your questions here.

Non-Finite And Compound Forms

These forms show up all the time in real Spanish, especially when you are talking about actions in progress or things you have already done.

Form	English Meaning	Example Sentence
agregar	to add	Necesito agregar una foto al documento. I need to add a photo to the document.
agregando	adding	Estamos agregando nuevos clientes. We are adding new clients.
agregado	added	Ya he agregado el enlace. I have already added the link.
he agregado	I have added	He agregado todos los cambios. I have added all the changes.
voy a agregar	I am going to add	Voy a agregar una advertencia. I am going to add a warning.

Useful Phrases With Agregar

These are the kinds of combinations that make agregar feel useful in actual adult life: cooking, work, apps, forms, presentations, and those suspiciously aggressive group chats.

Phrase	English Meaning	Example Sentence
agregar sal	to add salt	Primero, agrega sal al agua. First, add salt to the water.

Common Mistakes And Quick Fixes

• Writing agregé instead of agregué. The preterite yo form needs gu.
• Forgetting that agregamos has two jobs. It can be present or preterite, depending on context.
• Using present forms after triggers like quiero que or es posible que. Those often need the subjunctive: agregues, agregue, agreguemos.
• Mixing up commands and statements. Tú agregas means “you add,” but agrega means “add!”
• Treating agregar like a weird irregular verb. It really is mostly regular. The spelling change is tiny, not tragic.

FAQ

Why Is It Agregué And Not Agregé?

Because Spanish changes g to gu before e to keep the same hard sound. Without the u, the pronunciation would shift.

Is Agregar Regular Or Irregular?

It is best described as mostly regular. The endings follow normal -ar patterns, but some forms use the spelling change g → gu before e.

What Is The Difference Between Agregar And Añadir?

Both usually mean “to add.” In everyday Mexican Spanish, agregar sounds completely natural in speech, writing, tech, forms, and instructions.

Keep this one simple: agrego, agregué, agregue, agrega, agregando, agregado. That small set carries a lot of real Spanish, which is frankly a much better deal than memorizing fifty random forms and hoping for the best.
