Explanation

A gerund is a verb form that ends in "-ing" and acts as a noun.

It is formed by adding the suffix "-ing" to the base form of a verb.

Gerunds can function as subjects, complements, or objects of a sentence.

Examples:

• Singing is my favorite hobby. (Here, "singing" is a gerund and the subject of the sentence.)
• I love watching movies. (Here, "watching movies" is a gerund and the object of the verb "love".)
