• Thus is often more formal and can mean “in this way” or “as a result.”
• Therefore typically means “for that reason” and is often used to conclude a statement logically.

Breakdown and Usage

1. Thus

You’ve asked a great question about using “so that” and “in order to.” While they both show purpose or reason, each has its own subtle use that’s good to understand for clear communication. Let’s explore the differences together!

Key Difference

• “So that” is often used to show purpose or reason, usually with a subject and verb, and can imply a future outcome.
• “In order to” also shows purpose but is more direct and formal, often with a verb right after it.

Let’s dive into each one for a clearer picture!

1. “So That”

Meaning and Use:
“So that” links two parts of a sentence to show why something happens or the intended result of an action. It’s commonly followed by a subject and verb.

Examples:

• She saved money so that she could travel next summer.
  (Why did she save money? So she could travel.)
• I’m studying hard so that I can pass the exam.
  (The reason for studying hard is to pass the exam.)

Note: In some cases, “so that” suggests that the action is taken to achieve a future goal or outcome.

Usage Tip: Think of “so that” as providing a reason or purpose that involves someone doing something in the future.

2. “In Order To”

Meaning and Use:
“In order to” is a bit more formal and is used to express purpose or intention. It’s directly followed by a verb (infinitive form) and doesn’t include a separate subject or action.

Examples:

• She saved money in order to travel next summer.
  (Direct purpose: The action of saving was specifically for travel.)
• I’m studying hard in order to pass the exam.
  (The studying has a clear purpose: passing the exam.)

Note: “In order to” is interchangeable with “to” in many cases, but using the full “in order to” adds a bit more emphasis on purpose.

Usage Tip: Use “in order to” when you want to clearly point to the goal or intention of an action. It sounds a bit more formal than just “to.”

2. in order to reduce pollution

Pro Tip 🌟

A simple way to remember:

• Use “so that” when you have a subject and verb in both parts of the sentence.
• Use “in order to” when you’re introducing a purpose with just a verb.

What is a Split Infinitive?

In English, an infinitive is the base form of a verb with the word “to” in front of it, like “to run,” “to read,” or “to sing.” A split infinitive happens when another word, usually an adverb, is placed between “to” and the verb. For example:

• Split infinitive: “She decided to quickly leave.”
• Unsplit infinitive: “She decided to leave quickly.”

Splitting infinitives is often fine in modern English. However, in formal or traditional writing, some prefer to keep the “to” and the verb together.

Why Avoid Split Infinitives?

The preference for avoiding split infinitives dates back to traditional grammar rules based on Latin, where infinitives are a single word (and therefore unsplittable). Though this rule is less strict in contemporary English, many people feel unsplit infinitives sound more polished, especially in formal writing.

How to Avoid Split Infinitives

If you want to avoid split infinitives, here are a few simple strategies:

1. Move the Adverb After the Verb

In many cases, you can simply move the adverb after the verb without changing the meaning:

• Split infinitive: “She hoped to thoroughly understand the concept.”
• Revised: “She hoped to understand the concept thoroughly.”

2. Place the Adverb Before “To”

Another option is to place the adverb before “to,” which often preserves the meaning:

• Split infinitive: “He wanted to fully complete the project.”
• Revised: “He wanted fully to complete the project.”

This can feel a little formal but is still grammatically correct.

3. Rewrite the Sentence

Sometimes, rephrasing the sentence is the easiest way to avoid a split infinitive while keeping it clear and formal:

• Split infinitive: “They tried to completely ignore the noise.”
• Revised: “They tried to ignore the noise completely.”

🔑 Key Difference

• “Although” introduces a clause that expresses contrast, similar to “even though” or “despite the fact that.”
• “While” can also show contrast but is often used to emphasize simultaneous actions or differences between two things happening at the same time.

1. “Although”

• Purpose: To introduce a contrasting idea, often one that might seem unexpected or contradictory.
• Position in a Sentence: Usually at the beginning or middle of a sentence.
• Example Sentences:
  • “Although it was raining, we went for a walk.”
    • (Contrast: Rain might usually stop someone from going out, but they went anyway!)
  • “She passed the test, although she didn’t study much.”
    • (Contrast: It’s surprising she passed because she didn’t study much.)

2. “While”

• Purpose 1: To show contrast, often comparing two actions or states.
  • Example Sentences:
    • “While he likes rock music, she prefers jazz.”
      • (Contrast: They have different music preferences.)
    • “The beach was crowded while the park was empty.”
      • (Contrast: The beach and park had different conditions.)
• Purpose 2: To show two things happening at the same time.
  • Example Sentences:
    • “She was cooking while he was setting the table.”
      • (Two actions happening simultaneously.)
    • “While I studied, my brother watched TV.”
      • (Two activities happening at the same time but different from each other.)

🌟 Comparison of “Although” and “While”

Think of “although” as used mainly to emphasize contrast, where the second part of the sentence is somewhat unexpected. “While” also introduces contrast but often implies a comparison or simultaneous actions.
