Definition of Adverbs of Purpose

An adverb of purpose, also known as an adverbial of purpose or reason, explains why an action is performed. It answers the question “Why?” or “For what purpose?” It provides the intention, aim, or reason behind the verb’s action.

Adverbs of purpose are typically introduced by words or phrases like to (infinitive of purpose), in order to, so as to, for, so that, and in case. They add clarity and specificity to sentences by explaining the motivation behind an action.

Adverbs of purpose can be classified as adverbial clauses or adverbial phrases, depending on their structure. Adverbial clauses contain a subject and a verb, while adverbial phrases do not.

Function

The primary function of an adverb of purpose is to provide the reason or intention behind an action. It modifies the verb by explaining why the action is being carried out. This helps to provide context and understanding to the reader or listener.

Adverbs of purpose can also add emphasis or persuasive power to a sentence. By clearly stating the reason for an action, the speaker or writer can influence the audience’s perception of that action.

Contexts

Adverbs of purpose are used in a wide variety of contexts, including:

Formal writing: Essays, reports, and academic papers often use adverbs of purpose to clearly state the reasons behind arguments or actions.
Informal writing: Emails, letters, and blog posts can use adverbs of purpose to explain personal intentions or motivations.
Spoken language: Conversations, presentations, and speeches use adverbs of purpose to provide context and clarity to the audience.
Instructions and directions: Recipes, manuals, and guides use adverbs of purpose to explain the reason for each step.

Structural Breakdown

Adverbs of purpose can be constructed using different grammatical structures. The most common structures include infinitive phrases, “so that” clauses, “in order that” clauses, and “for” phrases.

Infinitive Phrases

An infinitive phrase consists of the word “to” followed by the base form of a verb. It functions as an adverb of purpose by explaining the reason for the action of the main verb. For example, “I went to the store to buy milk.” Here, “to buy milk” explains why the speaker went to the store.

Infinitive phrases are versatile and commonly used to express purpose concisely. They can be placed at the beginning or end of a sentence, depending on the desired emphasis.

“So that” Clauses

A “so that” clause is a subordinate clause that expresses the purpose of the main clause. It consists of the conjunction “so that” followed by a subject and a verb. For example, “I study hard so that I can pass the exam.” Here, “so that I can pass the exam” explains the purpose of studying hard.

“So that” clauses often include modal verbs such as “can,” “could,” “will,” or “would” to express possibility or intention.

“In order that” Clauses

An “in order that” clause is similar to a “so that” clause, but it is more formal. It consists of the conjunction “in order that” followed by a subject and a verb. For example, “She saved money in order that she could travel the world.” Here, “in order that she could travel the world” explains the purpose of saving money.

“In order that” clauses are often used in formal writing to express a clear and deliberate intention.

“For” Phrases

The preposition “for” can be used to introduce a phrase that expresses purpose. In this case, “for” is followed by a noun or a gerund (verb + -ing). For example, “I use this knife for cutting vegetables.” Here, “for cutting vegetables” explains the purpose of using the knife.

“For” phrases are generally used to express the intended use or function of something.

Types of Adverbs of Purpose

Adverbs of purpose can be categorized based on the specific conjunction or structure used to introduce them. The main types include those introduced by “to,” “in order to,” “so as to,” “for,” “so that,” and “in case.”

“To” Infinitives

As mentioned earlier, “to” infinitives are a common way to express purpose. They are concise and versatile, making them suitable for various contexts. They directly follow the verb they modify, explaining the reason for the action.

Example: “He went to the library to study.”

“In Order To”

“In order to” is a more formal alternative to “to” infinitives. It emphasizes the intention or goal behind the action. It is often used in formal writing or when a more deliberate tone is desired.

Example: “They worked hard in order to succeed.”

“So As To”

“So as to” is similar to “in order to” but is generally considered more formal. It is often used to express a specific and carefully considered purpose.

Example: “She arrived early so as to get a good seat.”

“For” (Preposition)

The preposition “for” can be used to indicate purpose when followed by a noun or gerund. This construction is often used to describe the intended use or function of something.

Example: “This room is for storage.”

“So That” (Conjunction)

The conjunction “so that” introduces a clause that explains the purpose of the main clause. This construction often includes modal verbs to express possibility or intention.

Example: “He saved money so that he could buy a car.”

“In Case”

“In case” introduces a clause that explains the purpose of taking a precautionary measure. It indicates that the action is being taken to prepare for a possible future event.

Example: “Take an umbrella in case it rains.”

Usage Rules

Using adverbs of purpose correctly involves understanding the specific rules and guidelines associated with each type of construction. Here are some key usage rules to keep in mind:

Infinitive Placement

Infinitive phrases can usually be placed at the beginning or end of a sentence. Placing it at the beginning can add emphasis to the purpose. However, placing it at the end is generally more common and natural.

Example: To improve his skills, he practiced every day. / He practiced every day to improve his skills.

Subject Agreement

When using “so that” or “in order that” clauses, ensure that the subject of the main clause and the subordinate clause are clear and logically related. If the subjects are different, make sure the sentence structure is clear to avoid confusion.

Example: She gave him money so that he could buy food. (Clear subject agreement)

Tense Consistency

Maintain consistent tense between the main clause and the adverbial clause of purpose. The tense of the verb in the “so that” or “in order that” clause should be appropriate for the tense of the main verb.

Example: He studied hard so that he could pass the exam. (Past tense in both clauses)

Formal vs. Informal Usage

“In order to” and “so as to” are generally more formal than “to.” Choose the appropriate construction based on the context and the desired tone of your writing or speech.

Example: (Formal) She prepared thoroughly in order to deliver a successful presentation. (Informal) She prepared thoroughly to deliver a successful presentation.

Avoiding Ambiguity

Ensure that the purpose is clear and unambiguous. Avoid using adverbs of purpose in a way that could lead to misinterpretation.

Example: (Unclear) He went to the bank. (Clear) He went to the bank to deposit money.

Using Commas

When an adverbial clause of purpose begins a sentence, it is usually followed by a comma. If it comes at the end of the sentence, a comma is generally not needed unless it adds clarity.

Example: So that he could catch the early train, he woke up at 5 a.m.

Advanced Topics

For advanced learners, understanding the nuances and complexities of adverbs of purpose can further enhance their language skills. Here are some advanced topics to explore:

Elliptical Clauses

Elliptical clauses are clauses where some words are omitted because they are understood from the context. In adverbial clauses of purpose, this often involves omitting the subject or the auxiliary verb.

Example: He studied hard so (that he) could pass the exam.

Negative Purpose

Expressing negative purpose involves indicating what one wants to avoid. This can be done using “lest” or “for fear that.”

Example: He ran quickly lest he should be late. / They hid the evidence for fear that the police would find it.

Variations in Word Order

While the standard word order is generally followed, variations can be used for emphasis or stylistic effect. However, care must be taken to ensure clarity.

Example: To succeed, hard work is essential. (Emphasis on the purpose)

Purpose vs. Result

It is important to distinguish between adverbs of purpose and adverbs of result. Adverbs of purpose explain the intention behind an action, while adverbs of result describe the outcome of an action.

Example: (Purpose) He exercised to get healthy. (Result) He exercised so that he became healthy.

FAQ
