Common Mistakes When Using ‘in conclusion’ in a Sentence
Many learners and even experienced writers misuse the phrase in conclusion by placing it in the wrong context, overusing it, or treating it as a universal transition for any ending. The most common mistakes include using it in informal conversation, adding it when the conclusion is obvious, or failing to match the tone of the surrounding text. This guide explains exactly how to avoid those errors and use in conclusion correctly in academic and professional writing.
Quick Answer: When and How to Use ‘in Conclusion’
Use in conclusion only at the end of a formal piece of writing, such as an essay, report, or speech, to signal that you are summarizing your main points. It should be followed by a comma and a sentence that restates your argument or key findings. Do not use it in casual emails, everyday conversation, or short paragraphs where the ending is already clear.
What ‘in Conclusion’ Actually Means
The phrase in conclusion is a transition that tells the reader or listener you are about to finish. It is formal and signals a final summary or closing thought. In academic writing, it is most appropriate in the final paragraph of an essay or research paper. In professional settings, it can be used in formal reports or presentations. It is rarely suitable for everyday conversation or informal emails.
Common Mistake 1: Using ‘in Conclusion’ in Everyday Conversation
One of the most frequent errors is using in conclusion when speaking casually with friends or colleagues. For example, saying “In conclusion, I think we should go to the Italian restaurant” sounds unnatural and overly formal. In conversation, simpler phrases like so, basically, or all in all work better.
Example of the Mistake
Incorrect: “In conclusion, the movie was really good.”
Correct: “So, the movie was really good.”
Common Mistake 2: Using ‘in Conclusion’ When the Ending Is Obvious
If your text is very short or the conclusion is already clear, adding in conclusion feels redundant. For instance, in a three-sentence email, using this phrase is unnecessary and can make your writing seem stiff.
Example of the Mistake
Incorrect: “I have attached the report. Please review it. In conclusion, let me know if you have questions.”
Correct: “I have attached the report. Please review it and let me know if you have questions.”
Common Mistake 3: Using ‘in Conclusion’ in the Middle of a Paragraph
In conclusion should only appear at the very end of your writing, not in the middle of a paragraph or as a transition between points. Placing it early confuses the reader because they expect the text to end immediately.
Example of the Mistake
Incorrect: “The study found significant results. In conclusion, the data supports the hypothesis. However, more research is needed.”
Correct: “The study found significant results. The data supports the hypothesis. In conclusion, more research is needed to confirm these findings.”
Common Mistake 4: Overusing ‘in Conclusion’ in Every Piece of Writing
Using in conclusion in every essay or report makes your writing repetitive. Vary your concluding transitions with phrases like to summarize, in summary, ultimately, or overall. This keeps your writing fresh and engaging.
Comparison Table: ‘in Conclusion’ vs. Alternatives
| Phrase | Formality | Best Used In | Example |
|---|---|---|---|
| In conclusion | Very formal | Essays, research papers, formal speeches | In conclusion, the evidence supports the theory. |
| To summarize | Formal | Reports, presentations, summaries | To summarize, the project met all goals. |
| Overall | Neutral | Emails, conversations, short writing | Overall, the event was a success. |
| All in all | Informal | Casual conversation, personal notes | All in all, it was a good day. |
| Ultimately | Formal to neutral | Academic and professional writing | Ultimately, the decision rests with the board. |
