Review Questions

• How does an infinitive phrase function within a sentence?
  • An infinitive phrase can serve multiple roles within a sentence. It can act as a noun, functioning as the subject or object; it can also serve as an adjective to modify a noun or provide additional information; or it can function as an adverb to explain why or how an action occurs. This versatility makes infinitive phrases essential for enhancing the depth and clarity of sentences.
• Compare and contrast infinitive phrases with gerund phrases and participial phrases in terms of their functions in sentences.
  • Infinitive phrases begin with the base form of a verb preceded by 'to' and can function as nouns, adjectives, or adverbs. Gerund phrases start with a verb ending in -ing and only function as nouns. Participial phrases start with a participle and act as adjectives. This difference highlights how each type of phrase contributes uniquely to sentence structure: infinitives add variety in action descriptions, gerunds indicate ongoing actions or states, while participials provide descriptive detail.
• Evaluate the importance of using infinitive phrases effectively in writing and how they can enhance sentence variety.
  • Using infinitive phrases effectively adds complexity and variety to writing. They allow for more nuanced expressions of ideas by clarifying actions and their purposes within sentences.
