What is an introductory phrase?

An introductory phrase is a phrase that appears at the beginning of a sentence and provides context or additional information about the main clause. These phrases can be used to set the tone, give background information, or provide detail about the subject of the sentence. Introductory phrases are often followed by a comma to separate them from the main clause of the sentence.

Examples of introductory phrases include: "In conclusion," "On the other hand," "After years of hard work," and "According to the study." These phrases can help to improve the flow of a sentence and make it easier for readers to understand the writer's intended meaning.
