Negation with نہیں and مت in Urdu

Overview

Urdu has two primary negation words: نہیں nahīṅ for negating statements and مت mat for negating commands (imperatives). At the CEFR A1 level, understanding these two negation strategies is essential for expressing what does not happen, what is not true, and telling someone not to do something.

A key structural feature of Urdu negation is that نہیں typically causes the auxiliary verb (ہے, ہیں, etc.) to be dropped from the sentence. This is different from English, where negation adds a word but does not remove existing elements.

A third, more literary negation word, نہ na, appears in formal writing, poetry, and certain fixed expressions. While less common in everyday speech, learners will encounter it in written Urdu.

How It Works

نہیں — Statement Negation

Placed before the main verb or where the auxiliary would be:

Positive	Negative	Note
وہ جاتا ہے۔ (He goes.)	وہ نہیں جاتا۔	Auxiliary ہے drops
میں خوش ہوں۔ (I am happy.)	میں خوش نہیں۔	Auxiliary ہوں drops
وہ آئے گا۔ (He will come.)	وہ نہیں آئے گا۔	Future retains گا

مت — Imperative Negation

Used with command forms:

Positive Command	Negative Command
بیٹھو! (Sit!)	مت بیٹھو! (Don't sit!)
جاؤ! (Go!)	مت جاؤ! (Don't go!)
بولیے! (Speak!)	مت بولیے! (Don't speak!)

نہ — Literary/Formal Negation

Formal prohibition	نہ جائیے	Please don't go

Common Mistakes

Using مت in Statements

• Wrong: وہ مت جاتا ہے۔
• Right: وہ نہیں جاتا۔
• Why: مت is only for commands (imperatives). نہیں is for declarative statements.

Keeping the Auxiliary After نہیں

• Wrong: وہ نہیں جاتا ہے۔ (grammatically possible but non-standard)
• Right: وہ نہیں جاتا۔
• Why: Standard Urdu drops the ہے/ہیں auxiliary after نہیں, though some speakers retain it for emphasis.

Using نہیں for Commands

• Wrong: نہیں بیٹھو! (Don't sit!)
• Right: مت بیٹھو!
• Why: Imperative negation specifically requires مت, not نہیں.

Placing نہیں in the Wrong Position

• Wrong: نہیں وہ جاتا۔
• Right: وہ نہیں جاتا۔
• Why: نہیں typically comes immediately before the verb or predicate, not at the start of the sentence.

Usage Notes

In conversational Urdu, نہیں alone can serve as a complete negative response: "Did you eat?" "نہیں۔" (No.) It is the basic word for "no."

The auxiliary-dropping rule has exceptions in emphatic speech. A speaker might say وہ نہیں آتا ہے with deliberate emphasis on the auxiliary to stress the point. However, the default is to drop it.

نہ appears frequently in poetry and formal prose. It also appears in compound expressions like نہ...نہ (neither...nor) and is required in subjunctive clauses of purpose or prevention.

Practice Tips

• Convert positive sentences to negative by inserting نہیں and removing the auxiliary. Drill this transformation.
• Practice مت with common imperatives: مت جاؤ, مت کرو, مت بولو.
• Read simple Urdu dialogues and identify all negative constructions, noting which negation word is used and why.
