Definition. A gerund is a verbal that ends in-ing and functions as a noun. Adjective: gerundial or gerundival. The term gerund is used in traditional grammar. Many contemporary linguists prefer instead to use the term-ing form.
However, since a gerund functions as a noun, it occupies some positions in a sentence that a noun ordinarily would, for example: subject, direct object, subject complement, and object of preposition. Gerund as subject: Traveling might satisfy your desire for new experiences. (Traveling is the gerund.)
