Conjunctions are essential tools in the English language, acting as the glue that holds sentences together and enhances coherence and flow in writing and speech. Among the various types of conjunctions, conjunctions of purpose serve the specific function of indicating the reason or intention behind an action. Understanding and using these conjunctions correctly can greatly improve your ability to express intentions and purposes in English. This article will delve into the various conjunctions of purpose, their correct usage, and provide examples to illustrate their application.
Understanding Conjunctions of Purpose
Conjunctions of purpose are used to show the purpose or reason for an action. They answer the question “why?” and are essential for adding clarity to your sentences. The most common conjunctions of purpose in English include: so that, in order that, so as to, in order to, and lest. Each of these conjunctions has its own specific usage and nuances.
So That
The conjunction so that is used to express purpose and is often followed by a modal verb like can, could, may, or might. It indicates the intention behind an action.
**Examples:**
– She saved money so that she could buy a new car.
– I am studying hard so that I can pass the exam.
In these examples, “so that” is used to explain the purpose of saving money and studying hard.
In Order That
Similar to so that, the conjunction in order that is also used to express purpose. It is more formal and often used in written English. It is also followed by a modal verb.
**Examples:**
– The government is increasing taxes in order that they might reduce the deficit.
– She left early in order that she could catch the first train.
In these sentences, “in order that” explains the purpose behind increasing taxes and leaving early.
So As To
The conjunction so as to is used to express purpose and is always followed by an infinitive verb. It is slightly more formal than simply using to.
**Examples:**
– He whispered so as not to wake the baby.
– She exercises regularly so as to stay healthy.
Here, “so as to” is used to explain the purpose of whispering and exercising.
In Order To
The conjunction in order to is another way to express purpose and is followed by an infinitive verb. It is often interchangeable with “so as to,” but it is slightly more formal.
**Examples:**
– He left early in order to avoid the traffic.
– She moved to the city in order to find a better job.
In these examples, “in order to” indicates the reason behind leaving early and moving to the city.
Lest
The conjunction lest is less common in modern English but is still used, particularly in formal or literary contexts. It means “to prevent something from happening” and is followed by a verb in the subjunctive mood.
**Examples:**
– She wore a raincoat lest she get wet.
– He spoke softly lest he be overheard.
In these sentences, “lest” indicates the action taken to prevent getting wet and being overheard.
Choosing the Right Conjunction of Purpose
Choosing the correct conjunction of purpose depends on the context, formality, and the relationship between the clauses. Here are some guidelines to help you make the right choice:
1. **Formality**: Use so that and in order that in more formal contexts. In order to and so as to are also formal but can be used in less formal contexts as well.
2. **Verb Form**: So that and in order that are followed by a clause with a modal verb. So as to and in order to are followed by an infinitive verb.
3. **Preventive Actions**: Use lest when you want to express preventive actions, especially in formal or literary contexts.

2. **Incorrect Verb Form**: Pay attention to the verb form that follows the conjunction. “So as to” and “in order to” should be followed by an infinitive verb, while “so that” and “in order that” are followed by a clause with a modal verb.
3. **Overusing Conjunctions**: Avoid using the same conjunction repeatedly in your writing. Mix them up to add variety and sophistication to your sentences.
