“Thus” is a word we often see in formal writing, but it can work in other settings too. Whether you want to use it in a research paper, an essay, or even informal writing, understanding how to use “thus” correctly can make your work smoother. This article will explain how to use “thus” at the beginning of a sentence, its meanings, alternatives, and examples.

What Does “Thus” Mean?

“Thus” is an adverb that often connects ideas. It shows cause and effect, how something happened, or what result came from it. When you use “thus,” you’re saying “as a result” or “therefore.”

For example:

  • The experiment was a success. Thus, we can apply the findings to real-life situations.

Here, “thus” tells us the conclusion based on the experiment’s success.

Is It Correct to Start a Sentence with “Thus”?

Yes, starting a sentence with “thus” is perfectly fine! In fact, it’s common in formal writing like academic papers, professional reports, and essays.

However, you need to make sure it fits the sentence. Use “thus” only when you’re showing a result, conclusion, or logical outcome.

When to Use “Thus” at the Start of a Sentence
