Here are some things to consider when deciding if it's the right choice:
* Tone: "Likewise" is a more formal word than "similarly." It might not be the best choice for casual writing or speech.
* Clarity: Ensure the connection between the previous sentence and the one starting with "Likewise" is clear to the reader. If the connection is tenuous, it might be better to choose a different word.
* Redundancy: Avoid using "Likewise" too frequently, as it can become repetitive.
Example:
"The first chapter focused on the history of the event. Likewise, the second chapter delved into the social impact."
Overall, starting a sentence with "Likewise" is a stylistic choice. Use it when it fits the context and feels natural, but don't be afraid to choose alternative words like "Similarly" or "In the same way" if they work better.
