Auxiliary Verb: "Do" & "Does"
'Do' और 'Does' का प्रयोग

Essential for Present Tense Questions and Negatives.

Concept: In Simple Present Tense, we use "Do" or "Does" when the sentence is Negative (No) or a Question.
(Present Tense में 'नकार' या 'प्रश्न' के लिए Do/Does का प्रयोग होता है।)

1. The Golden Rule: Who uses what?

It depends on the Subject.

Auxiliary	Subjects	Hindi Hint
DO	I, We, You, They, Plural Nouns (Boys, Cars)	बहुवचन + I/You
DOES	He, She, It, Singular Nouns (Ram, Cat)	एकवचन

2. Negative Sentences (Do not / Does not)

To say "No" in the present.

English Sentence	Hindi Meaning
I do not (don't) know.	मैं नहीं जानता हूँ।
She does not (doesn't) like tea.	उसे चाय पसंद नहीं है।
They do not play here.	वे यहाँ नहीं खेलते हैं।

3. Interrogative Sentences (Questions)

Put Do or Does at the start to ask a question.

Question	Hindi Meaning

⚠️ Important Rule for "DOES"

When you use Does, remove 's' or 'es' from the main verb.

❌ Does he plays? (Wrong)
✅ Does he play? (Right - 's' is removed because of Does)
❌ She does not goes. (Wrong)
✅ She does not go. (Right)

4. Using "Do" for Emphasis (जोर देना)

Sometimes we use "Do" in positive sentences just to emphasize a point.
