A study found that there’s been a 50% decline in the use of semicolons in the last 20 years. In fact, most people don’t even know how or when to use them. According to the study, 67% of students rarely or never use semicolons and more than 50% have no clue how to use them. Just 11% say they use them often.
FYI: Semicolons are used to link two independent clauses (complete sentences) that are closely related. For example: I have a big day tomorrow; I can’t go out tonight. They are also used to separate items in a complex list, especially when the items already contain commas.
