The simplest present simple question type: yes/no questions. Unlike wh-questions, there's no question word. The sentence just starts directly with Do or Does. The whole exercise comes down to one choice: which one matches the subject?
Yes/no questions are answered with a simple yes or no, with no question word like what or where. They start directly with Do or Does.
Word order: Do/Does + subject + base verb + …?
“Do you speak French?” “Does he play the piano?”
Do vs. does:
• I/you/we/they → Do: “Do they own a car?”
• he/she/it → Does: “Does it get cold there in winter?”
Short answers:
Yes/no questions are usually answered with a short answer, not a full sentence. “Do you speak French?” → “Yes, I do.” / “No, I don't.” “Does she play chess?” → “Yes, she does.” / “No, she doesn't.”
