Do you ever get confused when using "does" vs. "do"?
They're both forms of the verb "to do".
You can use "to do" as an action verb. For example:

And, you can use it to ask questions. For example:
Do I have to do the dishes?
Does anyone have the time?
Easy right?
Let's clear up the confusion between "does" vs. do" so you can ask questions the right way!
It's About the Subject
The verb "to do" is an irregular verb and it can cause confusion in the English language.
"Does"and "do" are the present simple forms of the verb "to do". You can use them as action verbs. For example:

Knowing whether to use "does" vs. "do"depends on the subject you use it with. In English, this is called "subject-verb agreement".
