Fix the Sentence: Wrong Conjunction Chosen (B1–B2)

Selecting appropriate connecting words is often challenging for English learners, and using the wrong ones can result in sentences that are hard to understand. This article explains how to identify and fix frequent errors with linking words, offering practical tips and examples to help you improve your writing. By learning how to use connectors such as however, therefore, although, and because correctly, you will be able to create smoother, more coherent sentences that clearly express your ideas and make your overall writing stronger.

Explanation of typical errors with wrong conjunction choice

Choosing the correct conjunction can be tricky for English learners, especially at the B1–B2 level. Many mistakes happen when students confuse the function of different linking words, such as “because,” “but,” “so,” “although,” and “and.” These errors can make sentences sound awkward or change the meaning entirely. It’s important to understand not just what each conjunction means, but also how it connects ideas in a sentence.

Common reasons for mistakes

• Translating directly from your native language, where conjunctions might work differently
• Not recognizing the specific relationship between two clauses (cause, contrast, addition, etc.)
• Confusing conjunctions that look or sound similar, like “because” vs. “so”
• Overusing a familiar conjunction instead of choosing the most accurate one

Frequent conjunction errors

Below are some typical examples of mistakes with linking words, along with a brief explanation of what often goes wrong:

• Using “because” when you need “so”: Incorrect: I was tired because I went to bed. (should be “so”)
• Mixing up “although” and “but”: Incorrect: Although it was raining, but we went outside.
• Replacing “if” with “when” (or vice versa): Incorrect: When you heat ice, it will melt. (should be “If” for condition)
• Using “and” for contrast instead of “but”: Incorrect: She is tall and her sister is short.
• Doubling conjunctions: Incorrect: Because he was late, so he missed the bus.
• Using “or” when you mean “and”: Incorrect: You can have tea or coffee and cake. (unclear meaning)
• Forgetting to use a conjunction at all, making two sentences instead of one connected idea
• Misplacing the conjunction at the start of a sentence when it shouldn’t be there
• Using “but” in place of “although” at the beginning of a sentence: Incorrect: But he was tired, he finished the race.
• Choosing “since” for time when it’s meant for reason (or vice versa)

How to avoid these mistakes

To prevent errors with linking words, always check what relationship you want to express—are you adding information, showing a reason, giving a result, or contrasting ideas? Practice by reading and listening to how native speakers use conjunctions in context. If you’re unsure which word to use, try rewriting the sentence in a different way or use simple sentences until you’re more confident.

Examples of sentences where logic and conjunction do not match

Choosing the correct conjunction is essential for clear and accurate communication. Sometimes, mistakes happen when the linking word does not fit the relationship between ideas. This can confuse the reader or listener, making the sentence sound awkward or even illogical. Below, you will find typical examples where the connector does not match the intended meaning, along with short explanations.

Common mismatches between logic and conjunction

• She was tired, but she went to bed early. ❌ (but is incorrect; so fits better, as the second action results from the first.)
• He studied a lot, because he failed the test. ❌ (because is misleading here; it suggests he failed because he studied, which is illogical. although or but would be appropriate.)
• I didn’t eat breakfast, or I was late for work. ❌ (or is wrong; so or because depending on intent.)
• She loves pizza, so she doesn’t eat it often. ❌ (so implies a logical result, but here, although or but would be more accurate.)
• We can go to the park, because it’s raining. ❌ (because does not make sense; although or but would fit if you want to show contrast.)
• He didn’t call me, so I was worried. ✅ (This is correct; the conjunction matches the logic.)
• They were hungry, but they ordered food. ❌ (but suggests contrast, but there is none; so is more logical.)
• She went home, although she finished her work. ❌ (although is not logical; after or when would be better.)
• It was raining, and I took my umbrella. ✅ (This is correct; both actions are logically connected.)
• I was tired, because I went to bed early. ❌ (Implies going to bed early caused tiredness; so or although may be better.)
• She can’t swim, but she goes to the pool. ✅ (Correct use of but for contrast.)
• He went out, or it was raining. ❌ (or is not appropriate; although or even though would be clearer.)

Summary of common errors and corrections

Below is a quick reference guide showing some typical mismatches and their logical alternatives:

When reviewing your writing, always check if the conjunction reflects the real relationship between ideas—contrast, cause, result, or addition. This helps your sentences sound natural and logical.

Guided steps to identify the relationship: time, reason, contrast, condition

Understanding how ideas connect in a sentence is essential when choosing the right conjunction. To avoid mistakes, focus on what links the two parts: are you talking about when something happens (time), why it happens (reason), showing differences (contrast), or describing a possible situation (condition)? Let’s break down how to recognize each type.

1. Identifying time relationships

When events are related by when they happen, look for clues like actions that follow each other or happen at the same moment.

• after → We went home after the movie ended.
• before → Wash your hands before you eat.
• when → Call me when you arrive.
• while → She cooked while he cleaned.
• as soon as → Call me as soon as you’re ready.
• until → Wait here until I return.
• since → We haven’t spoken since you moved.
• once → Once he finished, he took a break.

Ask yourself: Does the sentence describe the order or timing of events?

2. Spotting reason (cause and effect)

If one part of the sentence explains why the other happens, you’re dealing with a reason.

• because → He stayed home because he felt sick.
• since → Since it was late, we went home.
• as → As it was raining, we stayed inside.
• so → It was cold, so we wore jackets.
• for → She left early, for she had a doctor’s appointment.

Try to identify if the sentence answers “Why?” or “What caused this?”

3. Recognizing contrast

Contrast shows differences or unexpected results.

• but → He wanted to join us, but he was busy.
• although → Although it was cold, they went swimming.
• though → She tried hard, though she didn’t succeed.
• even though → Even though he was tired, he kept working.
• whereas → She loves tea, whereas he prefers coffee.
• while → He is very calm, while his brother is energetic.
• however → It looked easy; however, it was difficult.
• yet → He had no experience, yet he got the job.

Ask: Is the second idea surprising or different from the first?

4. Detecting condition

Conditional relationships describe what happens if something else is true or happens.

• if → If it rains, we’ll stay inside.
• unless → You can’t leave unless you finish.
• provided (that) → You can come provided that you’re quiet.
• as long as → You can stay as long as you follow the rules.
• in case → Take an umbrella in case it rains.
• even if → I’ll help you even if I’m busy.
• only if → He will come only if you invite him.

Does the sentence talk about a situation and its possible result?

Practical steps for sentence correction

• Read both parts of the sentence carefully.
• Decide what connects them: time, reason, contrast, or condition.
• Check which conjunction fits that relationship.
• Replace any incorrect linking word with the right one for the meaning.
• Re-read to ensure the sentence is logical and clear.

This approach helps you select the correct conjunction and avoid common mistakes.

Practice task: choose a better conjunction for each sentence

Improving your sentences often means picking the most suitable connector. Below you'll find a set of sentences where the conjunction used is not the best choice. Read each one carefully and decide which word fits best. Sometimes, more than one option could work, but try to choose the most natural or logical link for each situation.

Instructions

Read the sentences below. Each contains a conjunction that doesn’t fit well. Choose a better one from these options: and, but, because, so, although, while, since, unless, if, or, when. Write your answer in place of the incorrect word.

1. She was tired so she went to bed early, because she had a lot of work to finish.
2. I wanted to go to the park because it was raining heavily.
3. We can have cake but we can have ice cream.
4. He studied hard although he passed the exam with high marks.
5. Call me unless you arrive at the airport.
6. She wore a jacket when it was cold outside.
7. They didn’t go swimming and the water was too cold.
8. I will go to the party or I finish my homework.
9. He was late so he missed the bus.
10. You can’t enter the club because you have a ticket.
11. Take an umbrella since it starts to rain.
12. She likes tea but she likes coffee more.

Longer exercise: correct a short paragraph with multiple errors

When learning how to use conjunctions, it’s easy to confuse words like “and,” “but,” “or,” “so,” and “because.” This exercise helps you spot and fix mistakes in a short text where the wrong conjunctions have been chosen. Read the paragraph, identify which linking words are incorrect, and rewrite the passage with the correct ones.

Task: Find and correct the errors

Below is a paragraph with several conjunction errors. Some sentences use the wrong connector, which changes the meaning or makes the text confusing. Read carefully and decide which words should be replaced.

Paragraph:

I wanted to go to the park, but it was raining, or I stayed at home. My friend called me, so I didn’t answer because I was watching a movie and I was tired. Later, I felt bored, but I started reading a book or I enjoyed it a lot.

Instructions

• Read the paragraph above.
• Identify all the conjunctions that are used incorrectly.
• Rewrite the paragraph, replacing the wrong connectors with better choices.

Common conjunctions and their correct uses

• and – connects similar ideas
• but – shows contrast
• or – gives a choice/alternative
• so – shows result/consequence
• because – gives a reason
• although – introduces a contrast (like "but")
• while – shows contrast or simultaneous actions
• since – gives a reason or time
• if – introduces a condition
• unless – gives a negative condition
• when – indicates time
• as – gives reason or time
• yet – shows an unexpected contrast

Practice: Rewrite the paragraph

Try to rewrite the paragraph so that each sentence uses the most appropriate conjunction.

Answer key with explanations of why each conjunction works best

Choosing the appropriate conjunction is essential for clarity and logical flow in English sentences, especially at the B1–B2 level. Below, you’ll find detailed explanations for why one connector is the best fit in each example, focusing on meaning, sentence structure, and typical usage.

Common Conjunctions and Their Purposes

• And: Adds similar or related information.
• But: Shows contrast or an exception.
• Or: Offers alternatives or choices.
• Because: Explains a reason or cause.

• When: Refers to time.
• Before: Indicates something happens earlier in time.
• After: Indicates something happens later in time.
• Until: Shows something continues up to a point in time.
• Even though: Strong contrast, more emphatic than 'although'.
• As: Can mean 'because' or 'while', depending on context.
• Whereas: Highlights a difference between two facts.
• So that: Explains purpose or intention.
• Neither…nor: Connects two negative ideas.

Examples with Explanations
