Review Questions

• How do infinitive phrases function differently when acting as nouns compared to when they act as adjectives?
  • When infinitive phrases function as nouns, they can serve as subjects or objects in a sentence. For example, in 'To read is enjoyable,' the phrase 'To read' acts as the subject. In contrast, when they act as adjectives, they modify nouns by providing additional information. For instance, in 'She has a book to read,' the phrase 'to read' describes the noun 'book.'
• Discuss how infinitive phrases can enhance sentence structure and meaning in writing.
  • Infinitive phrases enhance sentence structure by adding layers of meaning and clarity. They allow writers to express purpose, intention, or motivation effectively. For example, using an infinitive phrase can clarify why an action is taken, making sentences richer and more informative. This ability to modify various parts of speech gives writers flexibility and variety in their language use.
• Evaluate the role of infinitive phrases in conveying modality without using modal verbs.
  • Infinitive phrases convey modality by expressing possibility, necessity, or intention without relying on modal verbs like 'can' or 'must.' For instance, saying 'To travel is essential for growth' suggests necessity through the infinitive phrase instead of using a modal verb. This allows for nuanced expression and can change how ideas are perceived by placing emphasis on actions or purposes rather than grammatical mood.
