This video eloquently explains how to unleash the semicolons power correctly.

Is it a comma?

Or is it a period?

In general, semicolons should be used to compartmentalize and connect relatable thoughts to each other.

For example, these sentences from the video:

With a little practice, semicolons can become a valuable tool in your writing skill set.
