Spanish Modal Verbs: Poder, Querer, Deber and More
Learn how Spanish modal verbs and modal-like structures work with the infinitive — from puedo hablar, quiero aprender and debes estudiar to tengo que trabajar, necesito practicar and suelo leer.
Why Spanish modal verbs matter
Modal verbs are essential for real communication. They help you say what you can do, want to do, must do, should do, need to do or usually do. For learners, the main grammar rule is simple but important: conjugate the modal verb and keep the following verb in the infinitive.
How to use this page
Use this page after the general Spanish verbs overview and the infinitive lesson. First learn the main modal meanings, then practise the full pattern: modal verb + infinitive.
Decide whether the sentence expresses ability, wish, obligation, advice, need or habit.
Use forms such as puedo, quieres, debe, tenemos que or necesitan.
Say puedo hablar, quiero aprender, tenemos que salir, not puedo hablo.
The core system: modal verb + infinitive
Ability
Use poder + infinitive to express ability or possibility.
Puedo hablar español. · Podemos ayudarte.
Wish or intention
Use querer + infinitive to express what someone wants to do.
Quiero aprender. · Quiere viajar.
Obligation or advice
Use deber, tener que or necesitar with the infinitive.
Debes practicar. · Tengo que estudiar.
Spanish modal verbs at a glance
Spanish does not have exactly the same modal system as English. Instead, Spanish uses several very common verbs and verbal expressions followed by the infinitive.
| Verb or expression | Main meaning | Structure | Example | English meaning |
|---|---|---|---|---|
| poder | can, be able to, may | poder + infinitive | Puedo hablar español. | I can speak Spanish. |
| querer | want to | querer + infinitive | Quiero aprender más. | I want to learn more. |
| deber | should, must | deber + infinitive | Debes estudiar hoy. | You should study today. |
| tener que | have to | tener que + infinitive | Tengo que trabajar. | I have to work. |
| necesitar | need to | necesitar + infinitive | Necesito practicar. | I need to practise. |
| soler | usually do something | soler + infinitive | Suelo leer por la noche. | I usually read at night. |
| saber | know how to | saber + infinitive | Sé conducir. | I know how to drive. |
Poder + infinitive: ability and possibility
Poder expresses ability, possibility or permission depending on context. It is followed by an infinitive and is often translated as “can”, “be able to” or “may”.
Puedo hablar español. — I can speak Spanish.
No puedo venir mañana. — I cannot come tomorrow.
¿Puedes ayudarme? — Can you help me?
Podemos empezar ahora. — We can start now.
Poder is also an irregular and stem-changing verb in the present tense: puedo, puedes, puede, podemos, podéis, pueden.
Querer + infinitive: wish and intention
Querer expresses wish, intention or desire. It is followed by the infinitive when someone wants to do something.
Quiero aprender español. — I want to learn Spanish.
¿Quieres salir? — Do you want to go out?
Quiere trabajar en Argentina. — He / she wants to work in Argentina.
Queremos practicar más. — We want to practise more.
Like poder, querer is stem-changing in the present tense: quiero, quieres, quiere, queremos, queréis, quieren.
Deber + infinitive: should, must and probability
Deber + infinitive can express duty, advice or obligation. In some contexts, it can also express probability.
Debes estudiar más. — You should study more.
Debemos salir temprano. — We should leave early.
No debes fumar aquí. — You must not smoke here.
Debe ser difícil. — It must be difficult / it is probably difficult.
For strong practical obligation, Spanish often uses tener que + infinitive. For softer advice, deber + infinitive is common.
Tener que + infinitive: obligation
Tener que + infinitive expresses practical obligation or necessity. It is one of the most common ways to say “have to” in Spanish.
Tengo que trabajar. — I have to work.
Tienes que estudiar. — You have to study.
Tiene que llamar al médico. — He / she has to call the doctor.
Tenemos que salir ahora. — We have to leave now.
Do not confuse tener que with possession. Tengo un libro means “I have a book”; tengo que leer means “I have to read”.
Necesitar, soler and saber with infinitives
Some common Spanish verbs are not always classified as strict modal verbs, but they behave in a similar way because they are followed by an infinitive and add meaning to the main action.
| Verb | Meaning | Example | Grammar note |
|---|---|---|---|
| necesitar | need to | Necesito estudiar. | Regular verb followed by infinitive. |
| soler | usually do something | Suelo leer por la mañana. | Common for habitual actions. |
| saber | know how to | Sé nadar. | Ability learned as a skill. |
| preferir | prefer to | Prefiero quedarme en casa. | Often followed by infinitive. |
| intentar | try to | Intento hablar más. | Action intention or attempt. |
Word order with Spanish modal verbs
In a modal-verb structure, the first verb is conjugated and the second verb remains in the infinitive. This pattern is very stable and very important.
Quiero aprender. — correct
Quiero aprendo. — incorrect
Podemos salir. — correct
Podemos salimos. — incorrect
Tengo que estudiar. — correct
Tengo que estudio. — incorrect
This is why the infinitive is central for modal verbs. Learn it here: Spanish Infinitive.
Pronouns with modal verbs
With modal verbs followed by an infinitive, object and reflexive pronouns can often go before the conjugated verb or attach to the infinitive.
Te puedo ayudar. / Puedo ayudarte. — I can help you.
Me quiero levantar. / Quiero levantarme. — I want to get up.
Lo debes leer. / Debes leerlo. — You should read it.
Nos tenemos que ir. / Tenemos que irnos. — We have to leave.

Modal verbs vs auxiliary verbs
Modal verbs and auxiliary verbs are related because both help another verb. The difference is that modal verbs usually express meaning such as ability, wish, obligation or need, while auxiliary verbs often build tense, aspect or voice.
Puedo hablar. — modal meaning: ability
Quiero hablar. — modal meaning: wish
He hablado. — auxiliary structure: perfect tense
Estoy hablando. — auxiliary structure: progressive form
