Expert writing Tips
Best practice
When referring to two subjects performing an action, ensure you use the plural form of the verb. For instance, instead of saying "both does", use "both do".
Common error
Avoid using the singular verb form "does" with "both", as "both" implies two subjects and requires a plural verb form like "do". For example, it's incorrect to say "both does"; the proper form is "both do".

FAQs
Why is "both does" considered grammatically incorrect?
The phrase "both does" is considered grammatically incorrect because "both" is plural and requires a plural verb form. The correct phrasing would be "both do", where "do" is the plural form of the verb.
What's the difference between "both do" and "each does"?
"Both do" indicates that two entities are performing the same action together or in a similar manner. "Each does" suggests that individual members of a group perform an action separately. Consider the nuance when choosing which is most fitting.
In what contexts might I see "both does" used, even though it's grammatically incorrect?
Although grammatically incorrect, "both does" might appear in informal speech or writing where strict grammatical rules are not always followed. However, in formal writing, it's best to use "both do" or other grammatically correct alternatives.
Are there situations where "both does" could be considered acceptable?
No, "both does" is generally not considered acceptable in standard English. There might be very specific, non-standard dialects where it appears, but in formal or professional contexts, "both do" should always be used.
