English Grammar Overview - Parts of Speech - Infinitive & Gerund
And now we'll have a look at both the infinitive and the gerund. Infinitive is the word "to", followed by the base form of the verb. We"ll typically use it after a verb, specifically verbs like "want" or "hope". We can make statements like "I want to go to the beach." We also have our gerund. Our gerund is a verb followed by "-ing", but specifically used as a noun within the sentence. We have a verb plus a gerund: "I enjoy playing poker." The main verb is "enjoy" and, although "playing" looks as if it's a verb, it's actually used as the noun within the sentence. We also can use it with a preposition followed by a gerund: "How about going to the beach?" We could also put it in the front of a sentence: "Smoking is bad for you." Again, the verb plus "-ing" can act as two things within the sentence. We've got the gerund, otherwise the noun in the sentence, "Smoking is bad for you." You've also got the verb plus "-ing" in the present participle form when in its main verb of the sentence. An example there of would be "I'm not smoking."
