A gerund is a word formed by adding the suffix –ing to a verb (swimming, driving, learning, jogging, writing)
Words that are formed in this way usually represent activities—either physical or mental. Examples include running, eating, thinking, wishing, and herding. Gerunds act like nouns, and nouns are the most common kind of sentence subjects. Therefore, gerunds can act as subjects, too.
