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.
Eating is the verb in the clause, while this cake is the object of the verb. Eating this cake acts as a noun phrase within the sentence as a whole, though; the subject of the sentence is the non-finite clause, specifically eating. Other examples of the gerund: I like swimming.
