Understanding the Adjectival Infinitive: Functions and Examples

Introduction

An adjectival infinitive is a grammatical structure where an infinitive verb (the base form of a verb preceded by "to") functions as an adjective in a sentence. It modifies a noun or pronoun, providing additional information about it.

This construction is common in English and helps add descriptive details without using a full relative clause. Understanding how adjectival infinitives work can improve sentence variety and clarity in writing.

Functions of Adjectival Infinitives

Adjectival infinitives typically:

1. Describe the purpose or intended use of a noun

   • She brought a book to read on the train. (The infinitive "to read" describes the purpose of the book.)

2. Indicate necessity or obligation related to a noun

   • There are many tasks to complete before the deadline. (The infinitive "to complete" modifies "tasks," showing what needs to be done.)

3. Replace a relative clause for conciseness

   • He is the best candidate to hire. (Instead of saying, "He is the best candidate who should be hired.")

Examples of Adjectival Infinitives

Here are more examples to illustrate their usage:
