Coordinating conjunctions join words, phrases, or clauses of equal grammatical rank and help signal the relationship between ideas. This guide covers the main coordinating conjunctions and shows how they are used in clear, simple sentences.

And

Use and to add one idea to another. It joins similar types of elements and shows that both things are true or both actions happen.

She(to plan) a trip to Italy and her brother(to join) her for part of the journey.

Ella está planeando un viaje a Italia y su hermano se unirá a ella en parte del viaje.

But

Use but to show contrast or an unexpected difference between two ideas. It joins clauses that oppose each other in some way.

Or

Use or to present a choice or alternative between two or more possibilities. It can join single words, phrases, or whole clauses.

So

Use so to show a cause-and-effect relationship where the second idea is a result of the first. It connects an action or situation to its consequence.

Nor

Use nor to continue a negative idea and add another negative option. It often follows neither or another negative element and joins two negative alternatives.

For

Use for to explain a reason or cause. It is more formal than because and connects an effect to its cause when placed between two main clauses.

Yet

Use yet to introduce a contrast that is unexpected or shows a surprising twist. It functions like but but often signals a sharper or more significant contrast.

Summary

Coordinating conjunctions—and, but, or, so, nor, for, and yet—link equal elements and signal relationships like addition, contrast, choice, cause, and more. Practice using each one in sentences to make your writing clear and coherent.
