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.
You might be confusing a gerund after to with the infinitive form of a verb which does require the helping verb to, as in to see, to hear, and to speak. A gerund has no helping verb. When it follows to, the to is a preposition and the gerund, working as a noun, is its object.
