Semicolons are correctly and effectively used when connecting related but independent clauses of a sentence.
The semicolon (;) is a punctuation mark that separates major sentence elements. A semicolon can be used between two closely related independent clauses, provided they are not already connected by a coordinating conjunction.
The semi colon is employed to connect similar ideas that are independently placed in sentences. If you join the ideas with a semi colon, you don't have to use conjunctions.
