Either… or or Neither… nor?

either .. or is a construction we use to show there is a choice between two different things, but you can only choose one, not both.

For example:-

You can have either beer or wine.

You can use either … or to give someone an ultimatum.

For example:-

Either you leave now or I’ll tell your wife!

neither … nor is a construction we use to show that two or more things are not true or possible.

For example:-

He drinks neither wine nor beer.
