How to Say “What” in Japanese

The Japanese language, rich in nuance and context, presents a fascinating challenge when translating seemingly simple English words. Among these, the interrogative “what” offers a prime example of this linguistic depth. Depending on the grammatical function and the specific situation, “what” can manifest in several distinct Japanese forms. Mastering these variations is crucial for effective and natural communication, whether you’re a seasoned traveler, a language enthusiast, or an aspiring polyglot. This guide will delve into the primary ways to express “what” in Japanese, exploring their usage, grammatical roles, and subtle distinctions.

The Core Interrogatives: 何 (nani) and なん (nan)

At the heart of expressing “what” in Japanese lie the words 何 (nani) and なん (nan). While often used interchangeably in casual conversation, their pronunciation and application are not entirely arbitrary. Understanding their core difference, which is largely phonetic and dependent on the following sound, is the first step.

何 (nani)

何 (nani) is the most common and general translation for “what.” It functions as a pronoun, interrogative adjective, or interrogative adverb. Its versatility makes it indispensable in forming a wide array of questions.

As an Interrogative Pronoun

When “what” functions as the direct object or subject of a sentence, 何 (nani) is typically employed. It stands alone, asking for the identification of an unknown entity or action.

• Examples:
  • これは何ですか？ (Kore wa nani desu ka?) – What is this? (Here, 何 is the subject of the predicate “is.”)
  • 何を食べましたか？ (Nani o tabemashita ka?) – What did you eat? (Here, 何 is the direct object of the verb “eat.”)
  • 何をしますか？ (Nani o shimasu ka?) – What will you do? (Asking about an action.)

In these examples, 何 seeks to identify a thing, food, or action. The particles following it (は ‘wa’ for topic, を ‘o’ for direct object) clarify its grammatical role in the sentence.

As an Interrogative Adjective

何 (nani) can also precede a noun, modifying it and asking “what kind of” or “which.” In this usage, it functions as an interrogative adjective.

• Examples:
  • 何色の服が好きですか？ (Naniiro no fuku ga suki desu ka?) – What color clothes do you like? (何 modifies 色 ‘iro’ meaning color.)
  • 何曜日に会議がありますか？ (Naniyōbi ni kaigi ga arimasu ka?) – What day of the week is the meeting? (何 modifies 曜日 ‘yōbi’ meaning day of the week.)
  • 何人来ましたか？ (Naninin kimashita ka?) – How many people came? (Here, 何 is used with a counter, 人 ‘nin’ for people. While “how many” is the nuance, it stems from asking “what number of” people.)

When 何 directly precedes a noun, it is asking for a specific attribute or quantity related to that noun.

なん (nan)

The pronunciation of 何 changes to なん (nan) primarily when it is followed by certain sounds. This phonetic shift is a key aspect of Japanese pronunciation rules and aids in smoother speech flow. Generally, なん (nan) is used before sounds like ‘d’, ‘t’, ‘n’, and vowels.

Phonetic Context for なん (nan)

The rule of thumb is that if the word immediately following 何 begins with a ‘d’ sound (e.g., だ ‘da’, で ‘de’, ど ‘do’), a ‘t’ sound (e.g., た ‘ta’, て ‘te’, と ‘to’), an ‘n’ sound (e.g., な ‘na’, に ‘ni’, ぬ ‘nu’, ね ‘ne’, の ‘no’), or a vowel, then 何 is pronounced “nan.”

• Examples:
  • 何で学校に行きますか？ (Nan de gakkō ni ikimasu ka?) – How/By what means do you go to school? (Here, 何 is followed by で ‘de’. The meaning leans towards “how” or “by what means.”)
  • 何時から会議が始まりますか？ (Nanji kara kaigi ga hajimarimasu ka?) – From what time does the meeting start? (何 is followed by 時 ‘ji’.)
  • 何年生ですか？ (Nannensei desu ka?) – What grade are you in? (何 is followed by 年生 ‘nensei’.)

Semantic Nuances of なん (nan)

While the primary distinction is phonetic, there are subtle semantic leanings. When 何 is pronounced “nan,” the question can sometimes imply a broader scope or a more abstract inquiry compared to “nani.”

For instance, when asking about the means or method, “nan” often appears.

• Example:
  • 何でこの問題を解決しますか？ (Nan de kono mondai o kaiketsu shimasu ka?) – By what means will you solve this problem?

This distinction is not always rigid, and context often clarifies the intent. However, paying attention to the pronunciation shift can offer deeper insight into the speaker’s intended meaning.

Beyond the Basics: Contextual Variations and Other Expressions

While 何 (nani/nan) covers the majority of “what” expressions, Japanese also offers other ways to convey similar meanings, often with more specific implications.

何か (nanika) – Something

When you want to ask if someone wants “something” or if there is “something,” the construction 何か (nanika) is used. This implies an indefinite or unspecified item.

• Examples:
  • 何か飲み物はいかがですか？ (Nanika nomimono wa ikaga desu ka?) – Would you like something to drink?
  • 何か用事がありますか？ (Nanika yōji ga arimasu ka?) – Do you have something (specific) you need to do? / Is there something I can help you with?

Here, 何か implies an unknown or unspecified “something,” making the question less direct than asking “What specific drink would you like?”

何も (nanimo) – Nothing (in negative contexts)

Conversely, 何も (nanimo) is used in negative sentences to mean “nothing.”

• Examples:
  • 何も食べませんでした。(Nanimo tabemasen deshita.) – I didn’t eat anything.
  • 何も起こりませんでした。(Nanimo okorimasen deshita.) – Nothing happened.

This construction highlights the role of 何 in conjunction with particles to create different meanings.

Alternative Phrasings for Specific “What” Meanings

In certain situations, Japanese utilizes different words or phrases to capture specific aspects of “what.”

Which (as a form of “what”)

When “what” implies a choice from a limited set, the word どれ (dore) or どちら (dochira) might be more appropriate, though these are technically “which.” However, in some contexts, 何 can also be used to elicit a choice.

• Example:
  • この中で何が一番好きですか？ (Kono naka de nani ga ichiban suki desu ka?) – Among these, what do you like the most? (Here, “nani” is asking for the most liked item from a presented group.)

What kind of

As seen with 何色 (naniiro) and 何曜日 (naniyōbi), 何 can be combined with nouns to ask “what kind of.” Other examples include:

• Example:
  • 何の仕事ですか？ (Nani no shigoto desu ka?) – What kind of work do you do?

Formal vs. Informal Usage

The basic structure of asking “what” remains consistent across formality levels, with the particle か (ka) being omitted in informal speech.

• Formal: これは何ですか？ (Kore wa nani desu ka?)
• Informal: これ、何？ (Kore, nani?)

The use of です (desu) and ます (masu) forms also indicates formality.

Navigating Complex “What” Questions

As you delve deeper into the Japanese language, you will encounter more nuanced ways of asking “what.” Understanding the core何 (nani/nan) is fundamental, but recognizing the influence of particles, surrounding sounds, and specific contexts will elevate your fluency.

The Role of Particles with 何

Particles play a crucial role in defining the function of 何 within a sentence.

• ～は (wa): Marks 何 as the topic.
  • 何はともあれ、始めましょう。(Nani wa tomoare, hajimemashō.) – Regardless of what, let’s begin.
• ～を (o): Marks 何 as the direct object.
  • 何を見たいですか？(Nani o mitai desu ka?) – What do you want to see?
• ～が (ga): Marks 何 as the subject, often when the subject is unknown or the focus of the sentence.
  • 何が起こったのですか？(Nani ga okotta no desu ka?) – What happened?
• ～に (ni): Can indicate the indirect object or purpose.
  • 何に使うのですか？(Nani ni tsukau no desu ka?) – What is it used for?
• ～へ (e) / ～に (ni): Indicates direction.
  • 何へ行きますか？(Nani e ikimasu ka?) – Where are you going? (While literally “to what,” it functions as “where” in this context.)

The Interplay of何 and Count Nouns

When asking about the quantity of something, 何 combines with counter words.

• Examples:
  • 何冊の本を読みましたか？ (Nanisatsu no hon o yomimashita ka?) – How many books did you read? (冊 ‘satsu’ is a counter for books.)
  • 何台の車がありますか？ (Nandai no kuruma ga arimasu ka?) – How many cars are there? (台 ‘dai’ is a counter for machines/vehicles.)

Idiomatic Expressions

Certain idiomatic expressions utilize 何 to convey specific meanings that might not be direct translations of “what.”

• Example:
  • 何でもいいです。(Nan demo ii desu.) – Anything is fine. / It doesn’t matter what. (Here, 何でも ‘nan demo’ signifies generality.)

Mastering “what” in Japanese is a journey that involves understanding phonetic shifts, the grammatical roles of particles, and the contextual nuances that differentiate various expressions. By consistently practicing and paying close attention to how native speakers use 何 (nani/nan) and its related forms, you will undoubtedly enhance your ability to communicate effectively and naturally in Japanese.
