Conjunctions are words that connect phrases, clauses, or words in a sentence. They help us combine ideas and make our writing clearer. Common conjunctions include and, but, and or. For example, in the sentence "I like apples and oranges," the conjunction and links the two fruits together. There are two main types of conjunctions: coordinating and subordinating. Coordinating conjunctions, like for and nor, join equal parts of a sentence. Subordinating conjunctions, such as because and although, connect a dependent clause to an independent clause. Understanding conjunctions helps improve our communication and makes our sentences more interesting.
