納得させる em 30 segundos
- Causative form of 'nattoku suru', meaning 'to convince'.
- Focuses on the result of the other person being satisfied.
- Commonly used in business, debates, and personal explanations.
- Requires logical reasoning rather than just emotional pressure.
The Japanese verb 納得させる (nattoku saseru) is the causative form of the verb 納得する (nattoku suru). While 納得する means 'to be convinced' or 'to understand and accept,' the causative form shifts the agency, meaning 'to make someone understand' or 'to convince someone.' It is a nuanced term that goes beyond simple persuasion; it implies reaching a state where the other party truly internalizes the logic or the necessity of a situation. In professional and personal contexts, it suggests a process of explanation that leads to genuine agreement rather than forced compliance.
- Grammatical Structure
- Noun + を + 納得させる (To convince [Noun])
- Core Nuance
- Achieving mutual understanding through logic and reasoning.
- Transitivity
- Transitive (Causative), requiring an object (the person being convinced).
「彼は粘り強い交渉で、ついにクライアントを納得させた。」
To truly understand 納得させる, one must look at the kanji. 納 (nō) means 'to obtain' or 'to settle,' and 得 (toku) means 'to gain' or 'profit.' Together, they signify 'obtaining understanding.' When you add the causative suffix させる (saseru), you are actively facilitating that 'obtaining' process for someone else. This is why it is often used in business settings where consensus (根回し - nemawashi) is vital. It is not just about winning an argument; it is about ensuring the other person feels satisfied with the conclusion.
「親を納得させるのは簡単ではない。」
Furthermore, the word carries a weight of responsibility. If you 納得させる someone, you are often seen as the one who provided the clarity. It is frequently paired with adverbs like 十分に (jubun ni - sufficiently) or 完全に (kanzen ni - completely) to emphasize the depth of the conviction. Unlike 説得する (settoku suru), which focuses on the act of persuading, 納得させる focuses on the result: the other person's state of mind.
「数字を使って上司を納得させる必要がある。」
- Usage in Debate
- Used when one's logic is so sound that the opponent has no choice but to agree.
- Usage in Sales
- Used when a customer accepts the price-to-value ratio of a product.
Using 納得させる correctly requires understanding the relationship between the speaker and the listener. Since it is a causative verb, it implies a certain level of influence. You are the 'agent' causing the 'change' in the other person's mindset. The most common sentence pattern is [Person A] が [Person B] を [Method/Reason] で 納得させる.
「エビデンスを提示して、周囲を納得させた。」
In formal writing or business reports, you might see it in the passive causative form (納得させられる), meaning 'to be made to understand' or 'to be convinced by someone else.' This is often used when you were initially skeptical but were eventually swayed by a powerful argument. For example, 'I was convinced by his passion' would be 「彼の熱意に納得させられた。」
- Common Particles
- を (o): Marks the person being convinced.
で (de): Marks the means (logic, evidence, explanation). - Politeness Levels
- Dictionary: 納得させる
Polite: 納得させます
Te-form: 納得させて
When using this in a professional setting, it is often combined with auxiliary verbs to soften the tone. For instance, 納得させてみせる (I will show that I can convince them) or 納得させなければならない (I must convince them). It is a strong verb, so using it about your superiors requires care; instead of saying 'I will convince the CEO,' you might say 'I will seek the CEO's understanding' (ご理解をいただく).
「新しい企画について、チーム全員を納得させるのは時間がかかる。」
You will encounter 納得させる in various high-stakes environments. In Japanese dramas, particularly those focused on law (legal dramas) or corporate politics, this word is a staple. A lawyer might say, 'I will convince the jury' (陪審員を納得させる), or a detective might say, 'We need to convince the suspect to confess' (容疑者を納得させて自供させる).
「このデータなら、役員会も納得させることができるはずだ。」
In the workplace, it appears during performance reviews or project pitches. Managers use it when discussing how to handle difficult clients or internal stakeholders. It’s also common in educational settings, where a teacher aims to make students understand the logic behind a complex mathematical formula. If a student just memorizes it, they haven't been 'convinced' (納得していない); the teacher's goal is to 納得させる them of the underlying principle.
- News & Media
- Often used in political commentary regarding whether a policy 'convinces' the public.
- Daily Life
- Used when explaining a purchase to a spouse or a decision to a friend.
On social media and blogs, you'll see it in 'How-to' articles: 'How to convince people with your writing' (文章で人を納得させる方法). It is a key term in the psychology of communication. In anime, it often appears in shonen series where a protagonist has to convince a rival to join their cause through a combination of words and actions.
「自分自身を納得させるのが一番難しい。」
The most frequent mistake learners make with 納得させる is confusing it with 説得する (settoku suru). While they are related, 説得する is the *act* of trying to persuade, whereas 納得させる focuses on the *result* of the other person actually being satisfied with the explanation. You can 説得 (try to persuade) someone for hours without ever 納得させる (successfully convincing) them.
「× 彼を説得させた。」 (Incorrect if you mean you persuaded him yourself)
Another common error is the particle usage. Because it's a causative verb, some learners mistakenly use 'ni' for the person being convinced, thinking of it like 'give an explanation to.' However, since 納得する is treated as an intransitive state of mind, its causative takes 'o'.
- Particle Error
- Incorrect: 友達に納得させた。
Correct: 友達を納得させた。 - Nuance Error
- Using it for 'forcing' someone. 納得させる implies the other person agrees. If they don't agree but just obey, use 従わせる (shitagawaseru).
Learners also sometimes forget that 納得させる is quite formal. In very casual speech with close friends, you might say 'わからせる' (wakaraseru - make them understand), though this can sound a bit aggressive or condescending depending on the tone. 納得させる is safer and more respectful of the other person's intellect.
「× 無理やり納得させた。」 (Contradictory)
To master 納得させる, you should understand its synonyms and how they differ in nuance. The most prominent is 説得する (settoku suru). As mentioned, this is the process of persuasion. It's an action. You can say 'I am in the middle of persuading him' (説得中だ), but you wouldn't usually say 'I am in the middle of convincing him' (納得させ中) in the same way.
- 説得する (Settoku suru)
- To persuade. Focuses on the effort and the act of talking.
- 言い聞かせる (Iikikaseru)
- To tell/instruct. Often used from a superior to a subordinate or parent to child. It has a 'lecturing' nuance.
- 論破する (Ronpa suru)
- To defeat in an argument. This is aggressive and doesn't care if the other person is 'satisfied,' only that they are proven wrong.
「説得はしたが、納得させることはできなかった。」
Another similar term is 承諾させる (shōdaku saseru), which means 'to make someone give consent.' This is more legalistic and focuses on the formal 'yes' rather than the internal feeling of 'I understand.' Then there is 合意を取り付ける (gōi o toritsukeru), which means 'to secure an agreement,' commonly used in business contracts.
「彼は言葉巧みに相手を納得させる名人だ。」
