Understanding Coordinating Conjunctions

In English grammar, coordinating conjunctions connect words, phrases, or independent clauses that have equal grammatical importance. They help create smooth and balanced sentences.

What Are Coordinating Conjunctions?

The seven coordinating conjunctions in English are commonly remembered by the acronym FANBOYS: for, and, nor, but, or, yet, and so.

But	Shows contrast	It was cold, but we went out.
