Parts of a Sentence: Gerund Phrases

A phrase is a group of words that forms a unit simpler than a sentence. Unlike a sentence, or clause, a phrase does not contain both a subject and a finite (conjugated) verb. When building sentences, we use many types of phrases. This article focuses on gerund phrases.

What is a gerund?

A gerund is a type of verbal. (A verbal is a verb form that looks like a verb but does not act as the verb in a sentence.) A gerund ends in -ing and acts as a noun:

Swimming is good exercise.

[subject of verb is]

Aini likes fishing.

[object of verb likes]

You will gain skill by practising.

[object of preposition by]

What is a gerund phrase?

A gerund phrase is a gerund with attached words. For example, a gerund may take an object:

Swimming laps is good exercise.

[gerund swimming + object laps]

A gerund can also have modifiers such as adverbs or prepositional phrases:

Aini likes fishing from the dock.

[gerund fishing + prepositional phrase from the dock]

You will gain skill by practising the kazoo daily.

[gerund practising + object the kazoo + adverb daily]

A gerund with one or more objects or modifiers forms a gerund phrase.
Although gerund phrases do not contain a verb, they may have their own subjects (the person or thing doing the action in the gerund). The subject of a gerund is in the possessive form:

Sam appreciated my helping him.

Abdul was surprised at Tina's buying a Venus flytrap.

Can a gerund change its form?

Yes, we can use a gerund in a past form to show an action completed before another action:

Natalie was proud of having won the tournament.

[She won first; then she was proud]

Also, a gerund can be in a passive form:

Being introduced to Wayne Gretzky was a once-in-a-lifetime experience.

Irena was upset at having been passed over for the job.
