答える

The Japanese verb 答える (こたえる - kotaeru) is a fundamental word that every learner encounters early in their journey. At its core, it means 'to answer' or 'to reply.' However, its usage extends beyond simply providing a verbal response to a question. It encompasses the act of responding to stimuli, fulfilling expectations, or reacting to a specific situation. In the context of the Japanese Language Proficiency Test (JLPT), it is typically introduced at the N5 or N4 level, aligning with the CEFR A2 proficiency stage. Understanding 'kotaeru' requires a grasp of its grammatical requirements, specifically the use of the particle に (ni) to indicate what is being answered.

Grammatical Category

Ichidan Verb (Group 2). This means the dictionary form ends in 'eru', and conjugation is straightforward: drop 'ru' and add the suffix (e.g., kotae-masu, kotae-nai).

Core Meaning

To provide an answer to a question, a solution to a problem, or a response to a call or signal.

In daily life, you will hear this word in classrooms when a teacher asks a student to respond, in offices during meetings, and in casual settings when someone asks for your opinion. It is a 'transitive' verb in English logic but functions with the indirect object particle 'ni' in Japanese, which is a common point of confusion for English speakers who want to use 'o'.

Beyond verbal communication, 'kotaeru' can be used in more abstract ways. For instance, 'kitai ni kotaeru' means to live up to or meet expectations. This shows the depth of the word; it isn't just about words coming out of your mouth, but about your actions matching a prompt or a standard set by others. In a physical sense, 'kotaeru' can also describe how something affects the body, such as 'the cold is biting' (samusa ga kotaeru), though this is a slightly more advanced usage.

Social Nuance

Using 'kotaeru' implies a level of directness. In formal situations, you might hear 'o-kotae itashimasu' (I will answer) which uses humble language to show respect to the person asking.

When you are in Japan, you'll notice that silence is sometimes an answer, but when a verbal response is required, 'kotaeru' is the verb that describes that action. Whether you are taking a test (shiken ni kotaeru) or responding to a friend's text (though 'henji suru' is more common for messages), the concept of 'answering' is central to social harmony (wa). Not answering a question can be seen as rude or a sign of deep contemplation, depending on the context.

In summary, 'kotaeru' is a versatile verb that bridges the gap between simple classroom interaction and complex social expectations. It is the primary tool for indicating that a response has been given. As you progress in Japanese, you will find that 'kotaeru' pairs with many nouns to form essential collocations that describe how we interact with the world around us.

Common Collocations

1. 質問に答える (Answer a question)
2. 期待に答える (Meet expectations)
3. アンケートに答える (Respond to a survey)

Using 答える (kotaeru) correctly involves more than just knowing its meaning; you must master its conjugation and particle usage. As an Ichidan verb, its transformations are very predictable, making it a friendly verb for beginners. The most important rule to remember is the target of the answer. In English, we 'answer a question' (direct object). In Japanese, you 'answer TO a question' (質問に答える). This particle に (ni) is non-negotiable for standard usage.

Polite Form (Masu)

答えました (Answered), 答えます (Answers/Will answer), 答えません (Does not answer).

Plain Form (Dictionary)

答える (To answer), 答えた (Answered), 答えない (Does not answer).

When you want to ask someone to answer, you use the 'te-form' plus 'kudasai'. This is extremely common in educational settings. For example, 'Kono shitsumon ni kotaete kudasai' (Please answer this question). If you are in a more casual setting with friends, you might just say 'Kotaete!' (Answer me!).

Another important aspect is the 'potential form', which indicates the ability to answer. For 'kotaeru', the potential form is 答えられる (kotaerareru). You might use this when a question is particularly difficult: 'Muzukashikute kotaeraremasen' (It's so difficult I can't answer). In casual speech, this is often shortened to 'kotaereru', though 'kotaerareru' is the grammatically correct version.

Let's look at how 'kotaeru' behaves in negative sentences. If you refuse to answer, you might say 'Kotaetakunai' (I don't want to answer). This uses the '-tai' form (want to) in its negative state. In a formal context, if you are unable to provide an answer due to privacy or lack of knowledge, you would say 'O-kotae dekimasen' (I cannot answer), which is a very polite way to decline.

The verb can also be used in the passive voice, 答えられる (kotaerareru), though this is less common than the active voice. Usually, if a question 'is answered', we use different phrasing. However, you will see 'kotaeru' used with adverbs to describe *how* someone answers. 'Sugu ni kotaeru' (answer immediately), 'yukkuri kotaeru' (answer slowly), or 'hakkiri kotaeru' (answer clearly).

Adverbial Pairings

1. はっきりと答える (Answer clearly)
2. 丁寧に答える (Answer politely)
3. 即座に答える (Answer instantly)

In more complex sentences, 'kotaeru' can be the basis for a noun phrase. 'Kotae' (the answer) is the noun form. You can say 'Kotae o kaku' (write the answer). While 'kotaeru' is the action, 'kotae' is the result. It's important to distinguish between the two. You 'kotaeru' (verb) to a question to produce a 'kotae' (noun).

Finally, consider the 'causative' form: 答えさせる (kotaesaseru), meaning 'to make someone answer.' A teacher might 'kotaesaseru' a student. This shows the hierarchy often present in Japanese communication. Mastering these variations allows you to describe almost any scenario involving a response.

The word 答える (kotaeru) is ubiquitous in Japanese society, appearing in various registers from the highly formal to the very casual. If you are a student in Japan, the classroom is where you will hear it most frequently. Teachers will constantly use the imperative or polite request forms to prompt students. 'Tsugi no hito, kotaete' (Next person, answer) or 'Kono toi ni kotaerareru hito wa imasu ka?' (Is there anyone who can answer this inquiry?). It is the heartbeat of the educational exchange.

In Media

On variety shows and quiz programs like 'Panel Quiz Attack 25', the hosts will use 'kotaeru' to drive the action. You'll hear 'Seikai o kotaete kudasai!' (Please give the correct answer!).

In the business world, 'kotaeru' takes on a more professional tone. During press conferences, you will hear spokespeople say, 'Sono shitsumon ni wa o-kotae dekikanemasu' (I am afraid I cannot answer that question). The use of 'kaneru' adds a layer of formal hesitation and politeness. In customer service, if you ask a staff member a question they can't immediately resolve, they might say, 'Kakunin shite kara o-kotae shimasu' (I will answer after checking).

In literature and movies, 'kotaeru' is often used to describe a character's internal state or a dramatic revelation. A protagonist might 'kotaeru' to a call to adventure or a challenge from a rival. It's also used in the sense of 'responding' to someone's feelings. If someone confesses their love (kokuhaku), the other person's response is described using 'kotaeru'. 'Kanojo wa kare no omoi ni kotaeta' (She responded to his feelings/accepted his love).

You will also see 'kotaeru' in written form on surveys and forms. 'Ankēto ni kotaeru' (to fill out/answer a survey) is a common phrase found on websites and in stores. In these contexts, it's often written in kanji, so recognizing the character 答 is vital. The top part is the 'bamboo' radical, and the bottom is 'fit/join', suggesting a response that 'fits' the question.

In sports commentary, you'll hear about athletes 'responding' to the cheers of the crowd. 'Kansen no sei-en ni kotaete, hōmuran o uchimashita!' (Responding to the cheers of the fans, he hit a home run!). This usage highlights the 'reaction' aspect of the verb, showing that 'kotaeru' is about a dynamic relationship between a stimulus and a response.

Everyday Phrases

1. 「はい」と答える (To answer 'Yes')
2. 問いに答える (To answer an inquiry)
3. 呼びかけに答える (To respond to a call)

Finally, in legal or official settings, 'kotaeru' is used for testimony. A witness 'kotaeru' to the lawyer's questions. Here, the word carries the weight of truth and responsibility. Whether it's a child answering a simple 'What's your name?' or a politician answering for their policies, 'kotaeru' is the bridge of communication that connects two parties.

Even though 答える (kotaeru) is a basic verb, English speakers often stumble over a few specific points. The most frequent error is particle selection. In English, 'answer' is a transitive verb that takes a direct object: 'I answered the question.' This leads many students to say 質問を答える (shitsumon o kotaeru). However, in Japanese, you must use に (ni). Using 'o' sounds unnatural and is a clear marker of a non-native speaker.

Mistake #1: Wrong Particle

Incorrect: 質問を答える (Shitsumon o kotaeru)
Correct: 質問に答える (Shitsumon ni kotaeru)

Another common mistake is confusing 'kotaeru' with 'henji suru'. While both involve responding, they are not always interchangeable. 'Henji suru' is specifically for 'replying' to a message, a call, or a greeting. If someone says 'Hello' and you say 'Hello' back, that is 'henji'. If someone asks 'What is 2+2?' and you say '4', that is 'kotaeru'. Using 'kotaeru' for a simple 'Hello' or 'Yes' in response to your name being called is possible, but 'henji' is often more appropriate for the *act* of replying.

Learners also struggle with the difference between 'kotaeru' and 'kaitō suru'. 'Kaitō suru' (回答する) is a more formal, often written, version of 'answering'. It is used for official responses, exam answers, or technical solutions. If you use 'kaitō suru' in a casual conversation with a friend, you will sound like a textbook or a robot. Conversely, using 'kotaeru' in a formal scientific paper might seem a bit too simple.

A subtle mistake involves the 'potential' and 'passive' forms. Because 'kotaeru' is an Ichidan verb, both the potential ('can answer') and the passive ('is answered') are 'kotaerareru'. Context is the only way to distinguish them. However, learners often forget the 'ra' and say 'kotaereru'. While this 'ra-nuki' (dropped 'ra') is common in casual speech, it is technically incorrect in formal writing or exams.

Mistake #2: Confusing with 'Deru'

Incorrect: 電話に答える (Denwa ni kotaeru)
Correct: 電話に出る (Denwa ni deru)

Finally, be careful with the 'causative' form. 'Kotaesaseru' means 'to make/let someone answer'. If you use this incorrectly, you might accidentally imply you are forcing someone to speak when you just meant you 'asked' them. To simply 'ask' someone for an answer, use 'kiku' (to ask) or 'shitsumon suru' (to question).

To avoid these mistakes, practice 'kotaeru' as a set with 'ni'. Whenever you learn a new noun like 'shitsumon' (question) or 'kitai' (expectation), immediately pair it with 'ni kotaeru'. This muscle memory will prevent the 'o' particle slip-up and help you sound much more natural.

While 答える (kotaeru) is the go-to verb for 'answering', Japanese has several synonyms that are used in specific contexts. Understanding these nuances will elevate your Japanese from basic to proficient. The most common alternatives are 返事する (henji suru), 回答する (kaitō suru), and 応答する (ōtō suru).

返事する (Henji suru)

Used for 'replying' or 'responding' to a person. It's used for emails, letters, or when someone calls your name. It doesn't necessarily mean you are providing an 'answer' to a specific question, just that you are acknowledging the communication.

回答する (Kaitō suru)

A formal, often technical or official 'answer'. Used in exams (kaitō yōshi - answer sheet), surveys, or official government responses. It sounds more clinical and precise than 'kotaeru'.

Then there is 応答する (ōtō suru). This is often used in technical or emergency contexts, like 'responding' to a signal or a radio call. It's also used in 'ōtō-nashi' (no response/no answer), which you might hear in a police drama or when a computer system isn't responding. It focuses on the technical 'ping-back' nature of the response.

For 'answering' a phone, as mentioned before, the standard verb is 出る (deru). If you want to say 'respond to a request', you might use 応じる (ōjiru). This verb is more about 'complying' or 'agreeing' to something. For example, 'Rikuesuto ni ōjiru' (to grant a request). While 'kotaeru' can be used for 'expectations', 'ōjiru' is better for formal requests or demands.

Another interesting alternative is 言い返す (iikaesu), which means 'to talk back' or 'to retort'. This is a specific kind of 'answering' where you are arguing or defending yourself. It's much more aggressive than the neutral 'kotaeru'. Similarly, 答えを出す (kotae o dasu) means 'to come up with an answer' or 'to reach a conclusion', emphasizing the process of finding the solution rather than just the act of speaking it.

In summary, while 'kotaeru' is the most versatile, choosing the right synonym shows a deeper understanding of Japanese social context.
