なに

§ What does it mean and when do people use it?

Alright, let's talk about なに (nani). This is one of the first words you'll learn in Japanese, and for good reason. It means 'what'. Simple, right? But like many words, how you use it and how it sounds can change based on the situation. Knowing when and how to use なに (nani) correctly will make your Japanese sound much more natural.

Generally, なに (nani) is used to ask questions when you're looking for information about an object, an action, or a situation. Think of it as your go-to word when you're curious and need to know specifics.

DEFINITION

What.

You'll often hear なに (nani) at the beginning or middle of a sentence, followed by a particle or a verb. It's a core interrogative word, meaning it's used for asking questions. If you want to ask 'What is this?', 'What are you doing?', or 'What did you eat?', you'll be using なに (nani).

§ Basic Usage: Asking 'What?'

The most straightforward use is asking 'What is it?'.

Here, です (desu) is the polite copula (like 'is' or 'am'), and か (ka) turns it into a question. Very common. Another common way is asking about an action:

The を (o) particle marks なに (nani) as the direct object of the verb しています (shite imasu), meaning 'doing'. So you're asking 'what' is being done.

§ なに (nani) vs. なん (nan): The Important Distinction

This is where it gets a little tricky, but it's important. なに (nani) often changes to なん (nan) depending on the sound that follows it. Generally:

• Use なん (nan) before sounds that start with a t, d, or n sound, or before the particles 〜です (desu) or 〜だ (da).
• Use なに (nani) in other cases, especially before the particles を (o), が (ga), に (ni), へ (e), と (to), or から (kara).

Let's look at examples for both:

When to use なん (nan):

Here, です (desu) starts with a 'd' sound, so なん (nan) is used.

じ (ji), meaning 'time', starts with a 'j' sound (which is close to a 'd' sound in Japanese phonetics), so なん (nan) is preferred.

When to use なに (nani):

Here, the particle を (o) follows なに, so なに (nani) is used.

In this case, the particle が (ga) follows, so なに (nani) is used.

§ なに (nani) as an Exclamation

You might also hear なに (nani) used as a standalone exclamation, similar to 'What?!' or 'Huh?!' in English, expressing surprise or disbelief. This is typically informal.

This usage is very direct and informal. Use it with friends, not your boss.

§ Common Phrases with なに (nani) / なん (nan)

You'll encounter なに and なん in many common phrases. Here are a few to get you started:

• なんさいですか？ (Nan sai desu ka?) - How old are you? (さい (sai) starts with 's', but it's a common phrase where なん is used)
• なんていう？ (Nan te iu?) - What do you call it? / What did you say?
• なにか？ (Nani ka?) - Something? / Is there something? (Often implies 'Is there something you need/want?')
• なにNani mo arimasen) - There is nothing.

Understanding なに (nani) and its sibling なん (nan) is a fundamental step in building your Japanese vocabulary. Don't worry if the distinction between なに and なん feels a bit fuzzy at first. With practice and exposure, it will become second nature. Just remember to listen carefully to how native speakers use it, and try to mimic them. You'll get there!

§ Basic Questions with なに

The simplest way to use なに (nani) is to ask "what" directly. You can often see it at the beginning of a sentence or shortly after the topic marker. Remember, in very casual speech, particles can sometimes be dropped, but it's good practice to learn them.

Hint

What is it?

Hint

What is this?

§ なに with Particles

Particles are key in Japanese, and なに is no exception. Here's how it pairs with some common ones:

なにを (nani o)

Used when なに is the direct object of a verb. It answers the question "What?" regarding an action.

Hint

What will you do?

Hint

What do you want to eat?

なにが (nani ga)

Used when なに is the subject of a sentence, or when it emphasizes what is being questioned. It often asks "What is it that...?"

Hint

What do you want? (Literally: What is it that you want?)

Hint

What can this do? (Literally: What is it that this can do?)

なにで (nani de)

As an instrumental particle, 'de' indicates means or method. So なにで asks "By what means?" or "With what?"

Hint

How did you come? (Literally: By what did you come?)

Hint

With what will you write?

なにに (nani ni)

The particle 'ni' has several uses, often indicating a target or point in time. When combined with なに, it can mean "to what?" or "for what?"

Hint

Into what will you put it?

Hint

What will you use it for?

§ なに as "What Kind of?"

Sometimes, なに can act like an adjective to ask "what kind of" when it precedes a noun. In this context, it's often pronounced 'nan'.

Hint

What kind of book will you read?

Hint

What kind of sports do you like?

§ Common Phrases with なに

Here are a few useful phrases that use なに. These are good to memorize as they're very common in daily conversation.

• なにこれ？ (Nani kore?): What is this? (Very casual)

• なにする？ (Nani suru?): What are you doing? / What should we do? (Casual)

• なにか (nanika): Something / Anything. This is different from just なに. It implies an unspecified item.

Hint

Do you want to eat something?

Understanding when to use 'nani' versus 'nan' is a subtle but important part of sounding natural. Keep practicing these examples, and you'll get the hang of it!

§ Understanding なに (nani)

The Japanese word なに (nani) means "what." It's a fundamental question word you'll hear and use constantly. While it seems simple, there are nuances in its usage, especially when combined with particles or when it changes to なん (nan). This section focuses on practical situations where you'll encounter なに in everyday life, from work to school and even in the news.

DEFINITION

What.

§ At Work

In a professional setting, なに is essential for asking about tasks, information, or clarifying instructions. Here are some common scenarios.

You might use this when pointing to an unfamiliar document or object on your desk.

Notice how なに becomes なん when followed by certain counters, like じ (ji - time). This is a very common change.

なにか (nani ka) means "something" or "anything." It's a polite way to offer assistance.

§ At School/In Class

As a student, なに is invaluable for asking questions about lessons, homework, or general school life.

A direct way to ask for clarification on a word or phrase.

Essential for staying on top of your studies.

A common phrase teachers use to check for understanding.

§ In the News/Media

When watching the news or reading articles, なに is used to inquire about events, causes, or details.

A news anchor or reporter might ask this to get to the root of a story.

You might hear this when commentators are speculating on the implications of an event.

By actively listening for なに and なん in these contexts, you'll quickly become more familiar with their natural usage. Pay attention to the particle that follows, as that often determines whether it's なに or なん, and helps clarify what kind of "what" is being asked.

Let's talk about some common pitfalls when using なに. It's a simple word, but there are a few things to watch out for that can trip up learners.

§ なに vs. なん: The Sound Change

This is probably the most frequent mistake. Both なに and なん mean "what," but their usage depends on what comes after them.

DEFINITION

Use なに when it's followed by a particle like が (ga), を (o), or か (ka).

What is there? (What do you have?)

What will you do?

DEFINITION

Use なん when it's followed by a counter, certain particles like の (no) or で (de), or the verb です (desu).

What is it?

How old are you? (Literally: What age are you?)

§ Using なに in Place of Other Question Words

While なに is useful, it's not a catch-all for every question. Sometimes, beginners might try to use なに where a more specific question word is needed.

• Instead of いつ (when):

  〇 いつ行きますか？ (When will you go?)

  ✕ なにに行きますか？ (Incorrect for "When will you go?")

• Instead of だれ (who):

  〇 だれが来ますか？ (Who is coming?)

  ✕ なにが来ますか？ (Incorrect for "Who is coming?")

Always choose the most appropriate question word for the information you're trying to get.

§ Overusing なに for "Why"

Sometimes learners try to force なに to mean "why." While there are some advanced constructions where なに can be part of a "why" question (e.g., なぜ / どうして - which actually come from なに and どう), for simple questions, stick to the direct "why" words.

• Instead of なぜ (naze) or どうして (doushite) for "why":

  〇 どうして遅刻しましたか？ (Why were you late?)

  ✕ なに遅刻しましたか？ (Incorrect for "Why were you late?")

Focus on using the dedicated interrogatives for clarity. Mastering the subtle differences between these common words will make your Japanese sound much more natural and accurate.
