Expert writing Tips

Best practice

Avoid using the phrase "are between either" in formal writing. It is grammatically awkward. Use alternatives like "are among either" for clarity.

Common error

Don't use "are between either" when you actually mean a selection from a larger group. "Between" usually indicates a direct relationship between two distinct items, while "among" is better suited for a group of three or more. For instance, instead of saying "the choices are between either A, B, or C", consider "the choices are among A, B, and C."

FAQs

How to correctly use "between" and "either" in a sentence?

When offering choices, use "either... or" to present two options, and "between" to describe a range or relationship between two distinct items. Avoid using "are between either" as it's grammatically incorrect. For example, use "You must choose "either A or B"" or "the difference is "between A and B"".

What are some alternatives to the phrase "are between either"?

Instead of "are between either", consider using phrases like "are among either", "lie between either", or restructure the sentence for clarity. The best alternative depends on the intended meaning and context.

Why is "are between either" considered grammatically awkward?

The phrase "are between either" is redundant and combines elements that don't fit together well. "Between" typically implies a relationship between two items, and using "either" in the same construction creates an unnecessary and grammatically unsound phrase.

How does the context affect the best replacement for "are between either"?

The best alternative depends on what you're trying to convey. If you mean options to choose from, use "either... or". If you're describing a position, consider "lies between". For selections from a group, "are among" works better.
