Expert writing Tips
Best practice
Use "either parents" when you want to indicate that a condition or action applies to one parent or the other, but not necessarily both simultaneously. For example, "Contact "either parents" to confirm attendance."
Common error
Avoid using "either parents" when you mean to refer to both parents collectively. "Either parents" specifies one or the other, whereas "both parents" encompasses both individuals. For example, instead of "Either parents attended the meeting", say "Both parents attended the meeting" if both were present.
