Semicolons are used to separate two independent clauses that are closely related in meaning, but not connected with a coordinating conjunction (such as "and", "but", or "or"). They can also be used to separate items in a list when the items themselves contain commas.
Examples:
She loved reading classics; her favorite author was Jane Austen.
He bought apples, oranges, and bananas; grapes, strawberries, and blueberries; and a watermelon.
The storm was approaching; the waves were crashing against the shore.
Usage Tips:
Do not use semicolons to connect dependent clauses or phrases.
Do not use semicolons before coordinating conjunctions or after subordinating conjunctions.
Use semicolons sparingly and for specific purposes, to avoid making your writing appear overly formal or complicated.
