Nonfinite Clause

Overview

A nonfinite clause is a clause that contains a nonfinite verb form (such as an infinitive, gerund, or participle) and typically lacks an explicit subject. Unlike finite clauses, which express tense and agree with a subject, nonfinite clauses function within a larger sentence, often acting as noun phrases, adjective phrases, or adverbial phrases.

Key Concepts

The core components of nonfinite clauses are their verb forms:

• Infinitives: Usually preceded by ‘to’ (e.g., ‘to run’, ‘to eat’).
• Gerunds: Verb forms ending in ‘-ing’ that function as nouns (e.g., ‘running’, ‘eating’).
• Participles: Verb forms ending in ‘-ing’ (present participle) or ‘-ed/-en’ (past participle) that function as adjectives or in participial phrases (e.g., ‘running water’, ‘broken window’).

Deep Dive

Nonfinite clauses add complexity and conciseness to sentences. They can modify nouns, verbs, or entire clauses. For instance, in ‘I want to learn‘, ‘to learn’ is an infinitive nonfinite clause acting as the direct object. In ‘She enjoys swimming‘, ‘swimming’ is a gerund nonfinite clause also acting as the direct object. Participial phrases like ‘Running quickly, he caught the bus’ function adverbially, modifying the main clause.

Applications

Nonfinite clauses are essential for:

• Conciseness: Replacing longer finite clauses.
• Style: Adding variety and sophistication to writing.
• Expressing purpose, cause, or result: E.g., ‘He studied hard to pass the exam.’

Challenges & Misconceptions

A common challenge is distinguishing gerunds from present participles, as both use the ‘-ing’ form. The key is their function: gerunds act as nouns, while participles act as adjectives or part of participial phrases. Another misconception is that nonfinite clauses always lack subjects; sometimes, subjects are implied or present in specific constructions (e.g., ‘I saw him running‘).

FAQs

What is the difference between a nonfinite and a finite clause?

A finite clause has a verb that shows tense and agrees with a subject. A nonfinite clause uses an infinitive, gerund, or participle and lacks these features.

Can a nonfinite clause have a subject?

Typically, nonfinite clauses don’t have explicit subjects. However, constructions like ‘for me to decide’ or ‘I saw him running’ show subjects associated with the nonfinite verb.

Are gerunds and participles the same?

No. Both use ‘-ing’ forms, but gerunds function as nouns, while participles function as adjectives or in participial phrases.
