By now you're used to using infinitives (the form of a verb that ends in –AR, -ER, or –IR) in a variety of ways. However, did you realize that an infinitive can be used as a subject or the object of a preposition?
In English, when a verb is used as a verbal noun, an –ing word is used. Examples include, "I like singing," "Diving is fun," or, "Before eating, I washed the dishes." If you translated these directly into Spanish, you may be tempted to use the present participle (such as cantando, buceando, comiendo). This would be incorrect. Use the infinitive instead.

Verbs Followed by Spanish Infinitives
There are many, many verbs in Spanish that are followed by a preposition (usually a, de, or en) and an infinitive. Some of these include: enseñar a to teach (something)
You are already familiar with using the infinitive form of a verb after words like poder, saber, and querer. (Examples include: "Puedo hacerlo," "Sé nadar," and "Quiero ir.")
However, did you know that sensory verbs like to hear, to see, or to feel, are also followed by an infinitive? Watch out for the word order: the infinitive will come directly after the conjugated sensory verb, followed by the direct object.
