Conjunctions are the glue that holds sentences together. Without them, we would be forced to speak in short, choppy sentences.

1. Coordinating Conjunctions (FANBOYS)

Use these to connect two equal clauses: For, And, Nor, But, Or, Yet, So.
Example: I wanted to go to the park, but it started raining.

2. Subordinating Conjunctions

These connect an independent clause with a dependent clause (e.g., because, although, while, since, unless).
Example: We stayed inside because it was raining.

3. Correlative Conjunctions

These come in pairs (e.g., both...and, either...or, neither...nor).
Example: You can have either cake or ice cream.
