Yes, you can start a sentence with ‘then.’ In fact, using ‘then’ at the beginning of a sentence can add clarity to your writing by establishing a sequence of events or ideas.
For instance, if you’re narrating a story or explaining a process, beginning a sentence with ‘then’ can signal the next step or action. Here’s an example:
‘I completed my homework. Then, I went outside to play.’
However, it’s important to use it judiciously. Overusing ‘then’ at the beginning of sentences can lead to a choppy writing style. Make sure your writing flows naturally and that each use of ‘then’ serves a purpose in your overall narrative.
