Expert writing Tips
Best practice
Use "for either variant" when discussing results, characteristics, or applicability related to one of two possible versions or forms of something. Ensure the context clearly defines the two variants being referenced.
Common error
Avoid using "for either variant" when more than two variants exist, as it implies a choice or consideration limited to only two options. Use "for any variant" or "for all variants" if the statement applies to more than two.
