There are two main types of conjunctions that do this:
* Coordinating conjunctions: These are the words "for," "and," "nor," "but," "or," "yet," and "so," often remembered by the acronym FANBOYS.
* Subordinating conjunctions: These words introduce dependent clauses and signal a relationship between the dependent clause and the independent clause, such as "because," "although," "since," "while," "if," "when," "before," and "after."
Here are some examples:
* Coordinating conjunction: *The sun was shining, and the birds were singing.*
* Subordinating conjunction: *Because it was raining, we stayed inside.*
It's important to remember that a conjunction must be used in conjunction with proper punctuation, such as a comma or a semicolon, to ensure the sentence is grammatically correct.
