Introduction
The infinitive form of a verb is its most basic, unconjugated form. In Spanish, infinitives always end in -ar, -er, or -ir. Mastering the infinitive is essential because it plays numerous roles in sentence construction, acting as nouns, adjectives, or adverbs. A solid understanding of infinitives will greatly improve your ability to read, write, and speak Spanish accurately and fluently.
This article is designed to provide a complete overview of the Spanish infinitive, covering its various uses, rules, and common errors. By working through the explanations and examples, you’ll gain the confidence to use infinitives correctly and effectively in your Spanish communication.
Definition of the Spanish Infinitive
The Spanish infinitive is the non-conjugated form of a verb, equivalent to the “to [verb]” form in English (e.g., to speak, to eat, to live). It is the base form listed in dictionaries and serves as the foundation for all verb conjugations. Infinitives in Spanish always end in one of three endings: -ar, -er, or -ir.
The infinitive can function as a noun, adjective, or adverb within a sentence. Its versatility makes it a fundamental element of Spanish grammar.
It’s important to understand that the infinitive itself does not indicate tense or person; it’s simply the verb in its most basic form. These properties make it highly flexible and adaptable to various grammatical structures.
Structural Breakdown
The structure of a Spanish infinitive is straightforward: it consists of a verb stem and one of the three infinitive endings: -ar, -er, or -ir. The verb stem carries the core meaning of the verb, while the ending identifies it as an infinitive.
To conjugate a verb, you remove the infinitive ending and add the appropriate conjugation ending. For example, to conjugate hablar (to speak), you remove the -ar to get the stem habl-, and then add the appropriate ending based on the tense and person. Understanding this fundamental structure is crucial for mastering verb conjugation in Spanish.
Examples of Infinitive Structures
- -ar verbs: Hablar (to speak), Cantar (to sing), Bailar (to dance)
- -er verbs: Comer (to eat), Beber (to drink), Leer (to read)
- -ir verbs: Vivir (to live), Escribir (to write), Abrir (to open)
Uses of the Infinitive as a Noun
One of the most common uses of the infinitive is as a noun. When used as a noun, the infinitive can function as the subject, object, or complement of a sentence.
In these cases, it often (but not always) requires the definite article “el” before it.
When used as a subject, the infinitive performs the action of the verb. As an object, it receives the action of the verb.
As a complement, it provides additional information about the subject or object. Understanding these different roles is key to correctly using the infinitive as a noun.

Uses of the Infinitive with Prepositions
Infinitives are frequently used after prepositions in Spanish. Common prepositions that are followed by infinitives include a, de, en, con, para, and por. The meaning of the preposition-infinitive combination often expresses purpose, reason, or manner.
For example, a + infinitive can express purpose or intention, while de + infinitive can express a quality or characteristic. Understanding these nuances is crucial for interpreting and constructing accurate Spanish sentences.

Common verbs that take an infinitive complement include querer (to want), poder (to be able), deber (to must/should), necesitar (to need), and saber (to know how).
When using an infinitive as a verb complement, it’s important to understand the specific meaning conveyed by the main verb. For example, querer + infinitive expresses a desire, while poder + infinitive expresses an ability or possibility.

Uses in Periphrastic Verbal Constructions
Periphrastic verbal constructions involve combining an auxiliary verb with an infinitive, gerund, or participle to express different aspects of an action, such as beginning, duration, or completion. These constructions add nuance and complexity to Spanish verb usage.
Common auxiliary verbs used in periphrastic constructions with infinitives include ir a (to be going to), tener que (to have to), haber que (to have to/must), and deber de (to must/probably). These constructions provide a richer and more expressive way to convey meaning than simple verb conjugations.

Usage Rules
Several rules govern the proper use of infinitives in Spanish. One key rule is that infinitives are generally used after prepositions.
Another rule is that when an infinitive functions as a noun, it often requires the definite article “el” before it, although this is not always necessary. Additionally, certain verbs always require an infinitive complement.
Understanding these rules is essential for avoiding grammatical errors and constructing correct and natural-sounding Spanish sentences. Paying attention to these guidelines will significantly improve your accuracy and fluency.
Common Mistakes
One common mistake is using the conjugated form of a verb instead of the infinitive after a preposition. For example, incorrectly saying “Voy a que yo como” instead of the correct “Voy a comer”. Another mistake is omitting the preposition when it is required before an infinitive, such as saying “Necesito ir” instead of “Necesito ir a” (although this second example is technically incorrect as ‘necesitar’ does not require a preposition before an infinitive). A further error is using the infinitive when a subjunctive form is required, especially after certain conjunctions.
Avoiding these common mistakes will greatly improve the accuracy of your Spanish. Paying attention to the specific requirements of each verb and preposition is crucial for correct usage.
Correct vs. Incorrect Examples
The following table highlights common mistakes involving infinitives and provides the correct alternatives.
| Incorrect | Correct | Explanation |
|---|---|---|
| Voy a que yo como. | Voy a comer. | Use the infinitive after “a” to express intention. |
| Necesito ir a. | Necesito ir. | The verb ‘necesitar’ does not require a preposition before the infinitive. |
| Para que tú haces eso. | Para que hagas eso. | Use the subjunctive after “para que.” |
| Después de yo comí. | Después de comer. | Use the infinitive after “después de.” |
| Antes que yo salgo. | Antes de salir. | Use the infinitive after “antes de.” |
| Es importante que yo estudio. | Es importante que estudie. | Use the subjunctive after “es importante que.” |
| Me gusta que yo bailo. | Me gusta bailar. | When referring to a general activity you like, use the infinitive. |
| Quiero que tú vas. | Quiero que vayas. | The verb “querer” requires the subjunctive in the dependent clause when there is a different subject. |
| Puedo a hablar español. | Puedo hablar español. | The verb “poder” doesn’t need a preposition before the infinitive. |
| Debo de ir a la tienda. | Debo ir a la tienda. or Debo de estar en la tienda. | “Deber” signifies obligation, “deber de” signifies probability. |

FAQ
Here are some frequently asked questions about the Spanish infinitive.
- What is the difference between an infinitive and a conjugated verb?
An infinitive is the base form of a verb (e.g., hablar, comer, vivir), while a conjugated verb is a verb that has been modified to indicate tense, person, and number (e.g., hablo, comes, vivimos).
- When should I use the infinitive after a preposition?
Always use the infinitive after a preposition (e.g., a, de, en, con, para, por) to express the action or state related to the preposition.
- Is it always necessary to use “el” before an infinitive when it functions as a noun?
While it is common to use “el” before an infinitive functioning as a noun, it is not always necessary. The use of “el” often depends on the emphasis or specificity you wish to convey. Generally, if the infinitive is a general concept, ‘el’ is not necessary, but if it is a specific instance or subject, it is.
- What are periphrastic verbal constructions?
Periphrastic verbal constructions are combinations of an auxiliary verb with an infinitive, gerund, or participle to express different aspects of an action, such as intention, obligation, or duration. For example, ir a +
infinitive (to be going to) expresses a future intention.
