Time order words establish clarity in our writing and take readers on a clear and cohesive journey. These words work in academic writing, fiction writing, professional writing, and technical writing. Keeping a time order words list nearby will help you move an essay or story forward.
Time order words can be placed anywhere in a sentence. Their most popular placement is at the start of a paragraph. When they come at the start of a sentence of paragraph, they’re typically followed by a comma. For example, “In conclusion, the final product was spectacular,” or, “Consequently, it went on to become an international bestseller.”
