Verbals -Gerund

A gerund is a verbal that ends in -ing and functions as a noun. The term verbal indicates that a gerund, like the other two kinds of verbals (Participles, and Infinitives), is based on a verb and therefore expresses action or a state of being. 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.

A Gerund Phrase is a group of words consisting of a gerund and the modifier(s) and/or (pro)noun(s) or noun phrase(s) that function as the direct object(s), indirect object(s), or complement(s) of the action or state expressed in the gerund, such as:

Finding a needle in a haystack would be easier than what we're trying to do. The gerund phrase functions as the subject of the sentence.

Finding (gerund)

a needle (direct object of action expressed in gerund)

in a haystack (prepositional phrase as adverb) I hope that you appreciate my offering you this opportunity. The gerund phrase functions as the direct object of the verb appreciate.

my (possessive pronoun adjective form, modifying the gerund)

offering (gerund)

you (indirect object of action expressed in gerund)

this opportunity (direct object of action expressed in gerund)
