These are the correlative conjunctions that we must know.

• both…and…
• either…or…
• neither…nor…
• not only…but also…

These are conjunctions that are used in pairs. They can connect two words, phrases, or sentences.

We can use these at the beginning of a sentence.

• Both yoga and Jujitsu are great ways to exercise.

• Not only apples but also grains like oatmeal are a great source of fiber.
• Not only does she like baseball, but she also likes basketball.

When we use "or" and "nor", use the be verb "is" and add an "-s" to the end of action verbs. We treat the two things as separate things. However, when we use "both…and…" then we consider them together.

• Either pizza or chicken is good.
• Both pizza and chicken are good.

We can also use these in the middle of a sentence.
