Question 1

When do I use Do vs Does in questions?

Accepted Answer

Use "Do" with I, you, we, and they. Use "Does" with he, she, it, and singular nouns. For example: "Do you like pizza?" but "Does she work here?"

Question 2

What is the word order for present simple questions?

Accepted Answer

The word order is: Do/Does + subject + base verb (infinitive without "to"). For example: "Does he play football?" not "Does he plays football?"

Question 3

Why do we use the base form after Do/Does?

Accepted Answer

The auxiliary verb Do/Does already carries the tense and person information, so the main verb stays in its base form. "Does she work?" is correct, not "Does she works?"

Question 4

How do I form negative questions in present simple?

Accepted Answer

Add "not" after Do/Does: "Do you not like it?" or use the contraction: "Don't you like it?" / "Doesn't she know?"

Question 5

What are common mistakes with present simple questions?

Accepted Answer

Common mistakes include: using "Does" with plurals ("Does they work?" - wrong), adding -s to the main verb ("Does she works?" - wrong), and forgetting the auxiliary ("She works here?" - informal only).
