Gerunds and Infinitives are commonly used sentence structures in English. They are the categories of non-finite verbs that can be used as a noun or an object in a sentence.
Gerunds and infinitives are sometimes referred to as verb complements. They may function as subjects or objects in a sentence.
Gerunds and Infinitives both function as nouns. They can act as the subject of a verb when placed before it, and as an object when placed after it.
Gerund is a verb form that ends in ‘-ing’ and is used as a noun in a sentence. E.g. playing, going, making, writing etc.
Infinitive is the base form of a verb preceded by ‘to’ E.g. to play, to go, to make, to write etc.
