なに / なん — What (Japanese Interrogative Pronoun)

Meaning & Usage

なに (nani) and なん (nan) are two pronunciations of the same Japanese question word. Both are written with the kanji 何, and both mean "what." They appear in almost every real-life conversation — asking "What is this?" at a restaurant, "What time is it?" on the street, or "What do you like?" when meeting someone new.

The central question for beginners is: when do I say なに and when do I say なん? The answer depends entirely on what sound follows the word. Japanese naturally favors smooth, flowing sounds, so 何 shifts pronunciation depending on what comes next — much like how English uses "a" before consonants and "an" before vowels. Same word, different surface form.

Use なん when followed by:

• The copula だ or です: 何ですか (nan desu ka — "What is it?")
• The particle で meaning "by means of": 何で (nande — "by what means / how come")
• The noun-modifying particle の: 何の (nan no — "what kind of")
• Counter words such as 時 (ji — o'clock), 人 (nin — people), 月 (gatsu — month), 日 (nichi — day of the month), 歳 (sai — years old), 枚 (mai — flat objects), 番 (ban — number)

Use なに when followed by:

• The direct object particle を: 何を (nani wo — "what [object]")
• The subject particle が: 何が (nani ga — "what [subject]")
• The inclusive particle も in negative sentences: 何も (nani mo — "nothing / not anything")
• The question particle か alone: 何か (nanika — "something")
• As a standalone exclamation: 何！ (Nani! — "What?!")

In casual spoken Japanese, native speakers sometimes bend these rules. For JLPT N5 and standard polite speech, following these guidelines is your safest bet. With enough listening practice, the correct form will start to feel instinctive.

Worth noting: なに/なん is an open-ended question word — it asks about something without referencing any specific visible set of choices. Other question words handle narrower situations: どれ (dore) for "which one" when choosing from visible options, どんな (donna) for "what kind of," and いくら (ikura) for "how much" in terms of price. Knowing which word fits which situation sharpens your Japanese considerably.

Structure & Formation

The word 何 occupies the position of the unknown element — wherever the answer would slot in. In polite speech, the question particle か goes at the very end of the sentence. The key decision is always which form to use: なに or なん. Use the table below as a quick reference.

Here are the most essential なん + Counter combinations to memorize for N5:

• 何時 (なんじ / nanji) — what time / what o'clock
• 何分 (なんぷん / nanpun) — what minute / how many minutes
• 何人 (なんにん / nannin) — how many people
• 何月 (なんがつ / nangatsu) — what month
• 何日 (なんにち / nannichi) — what day of the month
• 何歳 (なんさい / nansai) — how old
• 何番 (なんばん / nanban) — what number
• 何枚 (なんまい / nanmai) — how many (flat objects such as paper, tickets)

Common Mistakes

Mistake 1: Using なに Before Counter Words

❌ なに時ですか。

✅ 何時ですか。(なんじですか)

Counter words always follow なん, never なに. Asking about time, quantities, or dates means 何 is always read as なん. The key counters to know: 何時 (nanji), 何人 (nannin), 何月 (nangatsu), 何日 (nannichi), and 何歳 (nansai). Repeat them until they feel automatic.

Mistake 2: Using なん Before the を Particle

❌ なんを食べますか。

✅ 何を食べますか。(なにを食べますか)

Before the direct object particle を, always use なに. The を particle does not trigger the shift to なん. Whenever you want to ask "what do you [verb]?" with an action verb, the pattern is なにを + verb + ますか. For example: 何を見ますか (nani wo mimasu ka — "What will you watch?") and 何を買いますか (nani wo kaimasu ka — "What will you buy?").

Mistake 3: Forgetting か at the End of Questions

❌ これは何です。

✅ これは何ですか。

Polite Japanese questions need the particle か at the end. Without it, the sentence reads as a flat declaration — "This is [something]" — rather than a question. Close friends in casual speech sometimes drop か and use a rising intonation instead, but in polite contexts and on the JLPT exam, always include it.

Mistake 4: Confusing なに with どれ or どんな

❌ 何が好きですか。(said while pointing at three specific dishes on a menu)

✅ どれが好きですか。(Which one do you like — choosing from visible options)

なに asks about something without pointing to a specific set of options. どれ ("which one") fits when you are choosing from a visible, defined set of items. どんな ("what kind of") asks about the nature or characteristics of something. Mixing these up can confuse your conversation partner. When the options are already laid out in front of you, reach for どれ instead of なに.

Mistake 5: Using なにも in Positive Sentences

❌ 何も食べます。(attempting to say "I eat everything")

✅ 何でも食べます。(I will eat anything / everything)

✅ 何も食べません。(I won't eat anything — correct use with a negative verb)

なにも is a negative pattern and must always pair with a negative verb — it means "nothing" or "not anything." To express the positive idea of "anything" or "everything," use なんでも instead. This distinction appears frequently in N5 listening and reading comprehension questions.

Cultural Notes

Tone of voice carries enormous weight when using なに in everyday conversation. Said with a gentle rising intonation — 何ですか (nan desu ka) spoken softly — it sounds friendly and curious. Blurt out なに！ with a flat or falling intonation, though, and it can sound rude or confrontational, like a sharp "What?!" in English. Japanese communication is deeply sensitive to how your voice carries meaning.

The phrase 何ですか (nan desu ka) is remarkably versatile. A shopkeeper uses it when a customer approaches — effectively "How can I help you?" A teacher uses it to invite a student's question. A parent uses it when a child calls out. With the right intonation, the phrase is genuinely welcoming, creating an open invitation rather than a demand.

Among friends, Japanese people often simply say なに？with a rising voice instead of the full polite structure. Young people also use the expression 何それ！ (Nani sore! — literally "What is that?!") to express surprise, disbelief, or amusement. You will encounter this constantly in anime, TV dramas, and casual conversation. It works like "Seriously?!" or "No way!" in English.

For learners from a Chinese-speaking background, the kanji 何 will look familiar — it shares the same character as Mandarin 何 (hé). The meaning overlaps, but the pronunciation and grammatical usage are uniquely Japanese. That shared written heritage can still serve as a useful memory anchor.

JLPT Tips

The N5 exam tests your ability to use basic interrogative words in context. Questions involving なに/なん appear frequently in the listening section, where you must understand a short conversation and identify what was asked. Pay close attention to the particle that follows 何 — it tells you both the correct pronunciation and the type of information being requested. Focus especially on 何時 (nanji), 何月 (nangatsu), and 何人 (nannin), since time and quantity expressions appear in nearly every N5 listening exam.

For the reading section, practice reading 何 in its kanji form without hesitation. Compound expressions like 何時 (nanji), 何月 (nangatsu), 何日 (nannichi), and 何番 (nanban) show up regularly in passages about schedules, forms, introductions, and directions. Reading them fluently is essential for finishing within the time limit.

Fill-in-the-blank questions often ask you to choose the correct interrogative word. The strategy: look at what the answer would be. Answer is a thing or category → なに/なん. Answer is a place → どこ. Answer is a time period → いつ. Answer is a person → だれ. Ask yourself what kind of answer the question expects, and the right word becomes clear.

The contrast between 何か (nanika) and 何も + negative (nani mo + negative) is a classic N5 exam pattern. Remember: 何か in a positive question or statement means "something," while 何も paired with a negative verb means "nothing." Seeing 何も followed by a positive verb in an answer choice is almost certainly a trap. Meanwhile, 何でも (nandemo — "anything/everything") in a positive sentence is the affirmative counterpart — the exam often tests whether you can distinguish all three patterns from one another.
