In Spanish, an infinitive verb is the most basic form of a verb, without being conjugated in any particular tense or mood. Infinitives are verbs that end in either -ar, -er, or -ir, and they are classified according to these endings. The infinitive is a non-personal form of the verb, which means that it isnt conjugated. In English, the infinitive form of verbs includes the preposition “to.” However, in Spanish, infinitives are only one word and do not require a preposition.

Infinitives in Spanish can function as a verb or a noun. They can be used after certain verbs, adjectives, and some expressions. Infinitives can also be used as the subject of a sentence, where the verb functions as a noun. In these cases, the infinitive is always singular and masculine. Infinitives are also used after a conjugated verb, such as after a modal verb or as complements of a verb.

In Spanish, infinitives can be used in the following ways:

• After a preposition such as antes de (meaning before), después de (meaning after), etc.
• In instructions that are aimed at the general public – for example in cookery books or on signs.
• As a noun, where in English we would use the -ing form of the verb.

Some common examples of infinitive verbs in Spanish include:

• Infinitive verbs ending in -ar: cantar (to sing), volar (to fly), nadar (to swim), soñar (to dream), abrazar (to hug), amar (to love), caminar (to walk), lavar (to wash), terminar (to finish), empezar (to start), besar (to kiss), estar (to be).
• Infinitive verbs ending in -er: correr (to run), comer (to eat), entender (to understand), creer (to believe), leer (to read), vender (to sell).
• Infinitive verbs ending in -ir: vivir (to live), escribir (to write), abrir (to open), recibir (to receive), salir (to go out), dormir (to sleep) .
