な

な means do not do; prohibition. It is a JLPT N4 Japanese grammar pattern used to express the N4 idea of “do not; prohibition command” in natural Japanese.

This grammar point often appears in conversation, written explanations, formal notices, and JLPT-style reading questions. If you want to express the N4 idea of “do not; prohibition command” in natural Japanese, な is a useful pattern to learn after the N5 basics.

What does な mean?

Use な when you want to express the N4 idea of “do not; prohibition command” in natural Japanese.

Natural translations include:

• don’t
• prohibition command
• do not; prohibition command

The exact English translation changes with context. Focus on what the grammar point does in the sentence first, then choose the English phrase that sounds natural.

How to form な

Verb dictionary form + な

Examples of the pattern:

• Verb dictionary form + な
• Verb dictionary form
• な

Pay attention to the word form before the pattern. Many JLPT N4 mistakes happen because the meaning is understood, but the grammar is attached to the wrong form.

When is な used?

Use な in situations like:

• explaining a condition, reason, decision, comparison, or time relationship
• making a sentence more specific than a basic N5 pattern
• understanding natural Japanese in conversation or reading

Tone and register:

• neutral unless the grammar itself is marked as casual, humble, honorific, or formal
• Common in daily speech, textbook examples, and JLPT N4 reading questions

な example sentences

• ここに入るな。 — Do not enter here.
• そのボタンを押すな。 — Do not press that button.
• 危ないから触るな。 — Do not touch it because it is dangerous.
• 試験中に話すな。 — Do not talk during the exam.
• あきらめるな。 — Do not give up.

Read the Japanese sentence first, then check the English translation. Try to notice what the grammar point contributes: condition, timing, limitation, possibility, decision, politeness, contrast, or emphasis.

Nuance of な

The key nuance is do not; prohibition command in a sentence-specific context.

This matters because な may look simple in English, but the Japanese form tells you whether the speaker is describing a time, a condition, a decision, a possibility, a contrast, or a social relationship.

For example:

• In context, な helps make the sentence more precise than a direct English translation.
• Compared with ないでください, it has a different focus even when both patterns appear in similar sentences.

な vs ないでください

Both な and ないでください can appear in related sentences, but they are different.

な:

• is the target JLPT N4 pattern in this lesson
• carries the specific nuance explained above

ないでください:

• is useful for comparison because learners often mix it up
• may use a different form, tone, or sentence focus

Quick contrast examples:

• Target pattern: ここに入るな。 — Do not enter here.
• Related pattern with ないでください: compare the form and ask whether the sentence is about timing, condition, ability, decision, contrast, or politeness.

If you are unsure which one to use, identify the main job of the sentence before translating it into English.

Common mistakes with な

Watch out for these mistakes:

• Using it with the wrong verb, noun, or adjective form
• Confusing it with ないでください because the English translation can look similar
• Translating it too literally instead of reading the whole sentence context

A good study habit is to write one short sentence and then change only the grammar point. This makes the difference between similar patterns easier to feel.

Is な on the JLPT?

Yes. な is connected to JLPT N4 grammar in this blog.

That means learners should be able to:

• recognize it in reading
• understand its nuance in context
• use it in simple original sentences

For test preparation, do not only memorize the English gloss. Practice identifying the words around the grammar point, because JLPT questions often test structure and context together.

Practice questions for な

Try making your own sentences with these prompts:

• Write one sentence using the basic pattern.
• Change the sentence into polite or casual style if possible.
• Compare it with the related pattern from the comparison section.

Keep the sentences short at first. Once the form feels natural, add time words, places, reasons, or contrast to make the sentence more realistic.

Learning path for な

Use な as part of your JLPT N4 obligation, request, and command grammar toolkit. Review the level of pressure in な: necessity, prohibition, command, request, or advice. Then compare it with softer request forms and stronger obligation forms so your sentence does not sound too casual or too forceful.

A good review order is: first make one short sentence with な, then compare it with なければいけない, and finally add なければならない or 必要がある to see how the nuance changes.

For practice, write one sentence that uses な in its most literal meaning, one sentence that changes the subject or time expression, and one sentence that contrasts it with one of the related patterns below.

• が必要 — shows a nearby level of obligation, command, advice, or request strength.
