Mastering Verbal’s: Infinitives, Participles, and Gerunds

Definition:

How to Form:

  • Bare infinitive: The verb without “to” (e.g., “run,” “eat”).
  • Full infinitive: “To” + base form of the verb (e.g., “to run,” “to eat”).

Infinitives (the base form of a verb, usually preceded by “to”) can appear in various positions within a sentence, depending on their grammatical role. Here are the common positions in which infinitives are used:


1. Infinitive as the Subject of a Sentence

An infinitive can act as the subject of a sentence, often placed at the beginning.

Examples:

  • To read is enjoyable.
  • To exercise regularly is important for health.

In these examples, the infinitives “to read” and “to exercise” serve as the subject of the sentence.


2. Infinitive as the Object of a Verb

Infinitives often function as the direct object of certain verbs. In this case, the infinitive follows the verb.

Examples:

  • She wants to learn Spanish.
  • He agreed to help with the project.

Here, “to learn” and “to help” are the objects of the verbs “wants” and “agreed.”


3. Infinitive as a Subject Complement

When used as a subject complement, the infinitive follows a linking verb (like “is,” “was,” etc.) and renames or identifies the subject.

Examples:

  • His dream is to travel the world.
  • Her goal was to finish the race.

The infinitives “to travel” and “to finish” describe or complement the subjects “dream” and “goal.”


4. Infinitive as the Object of a Noun or Adjective

Infinitives can follow certain nouns and adjectives, providing additional detail about them.

Examples:

  • She had a chance to win the competition. (Infinitive after a noun)
  • He was eager to start the project. (Infinitive after an adjective)

In these examples, the infinitives “to win” and “to start” modify the noun “chance” and the adjective “eager.”


5. Infinitive as an Adverb (Expressing Purpose)

Infinitives can also function as adverbs, often explaining why something happens or providing a reason. In these cases, the infinitive usually appears after the main verb.

Examples:

  • She went to the store to buy groceries.
  • They stayed late to finish their work.

In these sentences, the infinitives “to buy” and “to finish” express the purpose of the actions.


6. Infinitive After Certain Verbs + Object (Causative Construction)

Certain verbs such as “ask,” “tell,” and “want” are followed by an object and an infinitive.

Examples:

  • She asked him to leave.
  • They told the children to be quiet.

Here, the infinitives follow the verbs “asked” and “told,” after their objects “him” and “the children.”


7. Infinitive After “Too” or “Enough”

Infinitives can also appear after expressions with “too” and “enough.”

Examples:

  • He is too tired to work.
  • She was strong enough to lift the box.

In these sentences, the infinitives follow “too” or “enough” to complete the idea.

Here’s a table of different uses of infinitives with examples:

List of common verbs that are typically followed by infinitives (the “to + verb” form), along with example sentences:


What is a Participle?

How to Form:

  • Present participle: Add “-ing” to the base form of the verb (e.g., “running,” “eating”).
  • Past participle: Regular verbs usually add -ed (e.g., “played,” “walked”), while irregular verbs have specific forms (e.g., “written,” “drunk”).

In English, participles can occupy various positions in a sentence, depending on the function they serve. Here’s a breakdown of common positions and examples:

  • Present Participle (usually describes an action happening at the same time as the main verb)
    • Running quickly, he caught the bus.
  • Past Participle (often indicates a condition or reason)
    • Exhausted by the workout, she sat down to rest.
  • Participles can function as adjectives when placed before the noun they modify.
  • Present Participle
    • The burning candle flickered in the dark.
  • Past Participle
    • The broken vase lay on the floor.
  • In perfect and passive constructions, past participles combine with auxiliary verbs.
  • Past Participle
    • She has finished her homework.
    • The book was written by an expert.
  • This structure provides additional information about the noun.
  • Present Participle
    • The students studying in the library are very focused.
  • Past Participle
    • The car parked in front of the house is mine.
  • Often used in causative constructions or with certain verbs.
  • Present Participle
    • He left the door standing open.
  • Past Participle
    • She got her hair dyed.
  • Participles can reduce relative clauses for brevity.
  • Present Participle
    • The person living next door is a doctor. (instead of who lives next door)
  • Past Participle
    • The book written by her became a bestseller. (instead of which was written by her).

Gerunds:

What is a Gerund?

A gerund is the -ing form of a verb that functions as a noun in a sentence. Gerunds are unique because they retain verb-like properties while behaving grammatically as nouns.

  • Add “-ing” to the base form of the verb (e.g., “running,” “eating”).

Gerunds (the -ing form of a verb used as a noun) can appear in several positions within a sentence. Here’s a list of common gerund positions, with examples:

1. As the Subject of a Sentence

  • A gerund can act as the subject, describing an action or activity as a noun.
  • Reading books is her favorite hobby.
  • Swimming every morning keeps him fit.
  • Gerunds can serve as the direct object of certain verbs.
  • She enjoys painting landscapes.
  • They avoid eating junk food.

3. As the Object of a Preposition

  • When a gerund follows a preposition, it acts as the object of that preposition.
  • He’s good at solving puzzles.
  • They talked about going to the beach.

4. As the Subject Complement

  • Gerunds can function as a subject complement (also called a predicate noun) after linking verbs.
  • Her passion is dancing.
  • The main issue is getting there on time.

5. As the Object of a Possessive

  • Sometimes, gerunds are used as the object of a possessive pronoun.
  • I appreciate your helping me with the project.
  • His singing is really impressive.

6. In Appositive Phrases

  • Gerunds can appear in appositive phrases, renaming a noun with further detail.
  • Her goal, finishing the marathon, was finally achieved.
  • Their job, managing the project, required great skill.

7. After Certain Expressions or Phrases

  • Some fixed expressions are commonly followed by gerunds.
  • I’m interested in learning Spanish.
  • They look forward to meeting you.

In English, verbals—infinitives, gerunds, and participles—play a unique role by allowing verbs to function as other parts of speech, such as nouns, adjectives, or adverbs. Each verbal form brings versatility and depth to sentence structure. Gerunds function as nouns, often describing actions or activities in various syntactical roles. Infinitives, often beginning with “to,” can act as nouns, adjectives, or adverbs, expressing purpose, intention, or abstract ideas. Participles, with their present (-ing) and past (-ed or irregular) forms, typically act as adjectives or parts of verb phrases, adding descriptive detail to sentences.
