Expert writing Tips

Best practice

Always complete the "either...or" construction. For example, instead of "using either or", write "using either X or Y" to present a clear choice.

Common error

Avoid omitting the second part of the "either...or" construction. Saying "using either" without specifying the "or" option leaves the sentence unfinished and unclear.

Ludwig's WRAP-UP

In summary, "using either or" is grammatically incorrect because it omits the second element needed for the correlative conjunction "either...or". Ludwig AI confirms this, highlighting that the proper structure is "using either X or Y". While frequently found in contexts like Science and News & Media, its flawed grammar makes it unsuitable for formal or professional writing. To convey a choice between options, complete the phrase with the alternatives, like "using either...or" followed by the options.
