Ludwig's WRAP-UP

In summary, the phrase "either of both of these" is grammatically incorrect and should be avoided. As Ludwig AI points out, it combines the mutually exclusive concepts of "either" (one of two) and "both" (two of two), leading to redundancy and ambiguity. The analysis of example sentences demonstrates that more appropriate and clearer alternatives such as ""either of these"" or "both of these" should be used depending on the intended meaning. Although examples can be found in diverse sources, using this specific construction would be considered an error. Focus on clarity and correctness in your writing by using simpler and more grammatically sound phrasing.

FAQs
