B1 adjective #7,000 가장 일반적인 7분 분량

有意

Q: Can I use '有意' to describe a meaningful conversation?

No, you should use '有意義' (yūigigi) for that. '有意' is strictly for data or technical contexts.

Q: What is '有意差' (yūisa)?

It means 'significant difference.' It is a very common compound used in research and business reports.

Q: Is '有意' common in daily life?

Not really. You will hear it in news reports or read it in professional documents, but rarely in casual chats.

Q: How do I say 'statistically significant'?

You say '統計的に有意' (tōkeiteki ni yūi).

Q: What does '有意水準' mean?

It means 'significance level,' usually referring to the p-value (like 0.05) in statistics.

Q: Can '有意' mean 'intentional'?

Yes, but it is a very formal or old-fashioned usage. In modern Japanese, 'itoteki' is more common for 'intentional'.

Q: Is '有意' a noun or an adjective?

It can be both, but it's most often used as a na-adjective (有意な) or an adverb (有意に).

Q: What is the opposite of '有意'?

The technical opposite is '有意ではない' (not significant) or '偶然' (by chance).

Q: Why is '有意' used in psychology?

It often refers to '有意の学習' (meaningful learning), where new info is connected to existing knowledge.

Q: Does '有意' always involve numbers?

In 90% of cases, yes. It implies some kind of objective comparison or proof.

설명 有意 in your Level:

At the A1 level, you don't really need to use '有意' (yūi). It is a very formal and academic word. However, you can think of it simply as 'having a big meaning' in a science way. You might see the first kanji '有' which means 'to have' and the second kanji '意' which means 'meaning' or 'mind.' For now, just remember that it's a word used by teachers and scientists when they talk about facts and numbers. You won't use it to talk about your hobbies or your family. If you see it in a book, just think: 'This is something important in a math way.'

At the A2 level, you might encounter '有意' (yūi) in very basic news reports or school textbooks. It is used to describe when something is 'not an accident.' For example, if many people get better after taking a medicine, a doctor might say there is a 'yūi-na sa' (a significant difference). It is important to know that this word is a 'na-adjective,' so you say '有意な' (yūi-na) before a noun. You should also start to distinguish it from 'yūigigi' (meaningful), which is what you use when you have a good day. '有意' is for data; '有意義' is for life.

As a B1 learner, you should understand '有意' (yūi) in the context of 'statistical significance.' This is its most common use in professional and academic Japanese. You will see it in phrases like '有意な差' (significant difference) or '有意に高い' (significantly higher). You should be able to recognize it in a business report or a news article about social trends. At this level, you should also be careful not to confuse it with '優位' (yūi), which means 'superiority' and is pronounced the same way. When you hear 'yūi,' check if the speaker is talking about data (有意) or competition (優位).

At the B2 level, you are expected to use '有意' (yūi) correctly in formal writing or presentations. You should understand the concept of '有意水準' (significance level, like p < 0.05) and be able to explain research results using '有意に.' You should also understand its nuance: it doesn't just mean 'big,' it means 'statistically proven.' If a result is '有意,' it means the null hypothesis has been rejected. You should be comfortable using it as an adverb ('有意に向上した') to describe trends in data or performance metrics in a business setting.

At the C1 level, you should have a nuanced grasp of '有意' (yūi) across different fields. In statistics, you understand '有意性' (significance) and '有意差' (significant difference) deeply. In philosophy or linguistics, you might encounter the more obscure use of '有意' meaning 'intentional' or 'purposive' (as in '有意の行動' - purposive action). You should be able to critique the use of the word, noting that 'statistical significance' (有意) does not always imply 'practical significance' (実用的重要性). Your usage should be precise, using '有意' only when objective data supports the claim.

At the C2 level, '有意' (yūi) is a tool you use with total precision in academic discourse or high-level professional environments. You are aware of the historical development of the term as a translation for Western scientific concepts during the Meiji era. You can use it in complex grammatical structures and understand its role in '帰無仮説の棄却' (rejection of the null hypothesis). You also recognize its presence in specialized terms like '有意抽出法' (purposive sampling) in sociology. You can navigate the subtle differences between '有意,' '有意義,' and '意味深' without hesitation, choosing the exact word for the register and context.

有意 30초 만에

Formal word for 'significant' or 'meaningful'.
Most commonly used in statistics (statistically significant).
Functions as a na-adjective (有意な) or adverb (有意に).
Not used for personal feelings; use 'yūigigi' for that.

The Japanese word 有意 (ゆうい - yūi) is a specialized term that functions primarily as a na-adjective or a noun. In its most literal sense, it translates to "having meaning" or "intentional," but in modern Japanese society, its usage has bifurcated into two distinct paths: a general academic sense of being "meaningful" and a highly specific technical sense used in statistics to denote "significance." For English speakers, the closest equivalent is the word "significant," but with a heavy emphasis on the mathematical or objective proof of that significance. When you encounter this word in a newspaper, a research paper, or a business presentation, it is almost certainly referring to a result that did not happen by chance.

Statistical Significance (統計的有意性): This is the most common use. It describes a situation where the difference between two groups or the result of an experiment is large enough that it is unlikely to be a fluke. For example, if a new medicine works better than a placebo, scientists look for a 有意な差 (yūi-na sa) or a "significant difference."
Intentionality (有意的): In philosophical or psychological contexts, it can refer to something done with a specific purpose or will. This is less common in daily conversation but appears in academic texts discussing human behavior.

新薬の治験において、統計的に有意な効果が確認された。
(In the clinical trials of the new drug, a statistically significant effect was confirmed.)

Understanding 有意 requires recognizing that it is not the same as the everyday word for "important" (重要 - jūyō) or "meaningful" in a personal sense (有意義 - yūigigi). While yūigigi describes a productive day or a worthwhile experience, yūi is cold, clinical, and data-driven. It asks: "Does this data point actually mean something, or is it just noise?"

両グループの平均値には、有意な差は認められなかった。
(No significant difference was observed between the average values of the two groups.)

The Kanji Breakdown: 有 (Yū): To exist, to have.
意 (I): Meaning, will, thought.
Together, they literally mean "possessing a specific meaning or will."

In a world of big data, this word has become a staple of corporate Japan. Marketing teams analyze whether a change in advertising led to a 有意な increase in clicks. Political analysts look for 有意な shifts in voter sentiment. It is a word of evidence and proof.

Using 有意 correctly depends on your ability to pair it with the right particles and nouns. Because it functions as a na-adjective, you will most frequently see it as 有意な (yūi-na) followed by a noun, or 有意に (yūi-ni) followed by a verb. It is almost never used in casual speech to describe feelings; instead, it is the backbone of formal reports and scientific discussions.

Pattern 1: 有意な + Noun: Used to describe a "significant" object or result.
Example: 有意な差 (Significant difference), 有意な結果 (Significant result), 有意な相関 (Significant correlation).
Pattern 2: 有意に + Verb/Adjective: Used to describe how something changed or exists.
Example: 有意に高い (Significantly higher), 有意に増加した (Significantly increased).

このデータは、統計学的に有意であると言える。
(It can be said that this data is statistically significant.)

When writing, remember that 有意 is often accompanied by the adverb 統計的に (tōkeiteki ni - statistically). This clarifies that you are talking about math rather than just a "big" difference. If you just say "big difference," you would use 大きな差. Using 有意な差 implies you have done the math to prove it.

昨年度と比較して、売上が有意に向上した。
(Compared to last year, sales have significantly improved [in a measurable way].)

In a sentence like "The difference is significant at the 5% level," the Japanese structure would be: 5%水準で有意である (Go-pāsento suijun de yūi de aru). This level of precision is where the word truly lives. It is the language of peer-reviewed journals and serious news broadcasts.

You won't hear 有意 while hanging out at a tachinomuya (standing bar) or during a casual lunch with colleagues. Instead, this word is a marker of formal, analytical, and professional environments. It is a keyword for anyone involved in STEM fields, social sciences, or data-driven business roles in Japan.

The Research Lab: Scientists use it constantly. During a lab meeting, a researcher might say, "有意差が出ませんでした" (Yūisa ga demasendashita), meaning "We didn't get a significant difference," which usually implies the experiment failed to prove the hypothesis.
Business Strategy Meetings: In a board room, when presenting market research, a consultant might highlight that a certain demographic shows a "有意な傾向" (yūi-na keikō - significant trend) toward a new product. This sounds much more professional and reliable than simply saying "many people like it."

この調査結果には、統計的な有意性は見られません。
(There is no statistical significance found in these survey results.)

You will also hear it on NHK News during segments about medical breakthroughs, economic shifts, or psychological studies. If a broadcaster says that a certain habit is 有意に related to longevity, they are telling the audience that this isn't just a rumor—it's backed by data. It lends an air of authority and objectivity to the statement.

Finally, in the world of psychology and linguistics, you might hear about "有意の学習" (yūi no gakushū), which refers to meaningful learning as opposed to rote memorization. However, this is quite niche. For 95% of learners, focusing on the "significant/statistical" meaning is the most effective path forward.

Because 有意 has several look-alike and sound-alike words, it is a minefield for intermediate Japanese learners. The most common errors involve confusing it with words that share one kanji or have the exact same pronunciation but different meanings.

Mistake 1: 有意 (Yūi) vs. 有意義 (Yūigigi): This is the #1 mistake.
Wrong: 有意な週末を過ごしました (I had a significant weekend).
Right: 有意義な週末を過ごしました (I had a meaningful/productive weekend).
Reason: 有意 is technical/statistical. 有意義 is for personal value and worth.
Mistake 2: 有意 (Yūi) vs. 優位 (Yūi): They sound identical.
有意: Significant (statistical).
優位: Superiority/Advantage (e.g., "Our company is in a superior position").
Context usually clarifies this, but in writing, the kanji are vital.

❌ この結果はとても有意です。
✅ この結果は統計的に有意です。
(Note: Without 'statistically,' 'yūi' sounds incomplete or overly formal in many contexts.)

Another mistake is using 有意 to mean "intentional" in everyday life. If you want to say "I did it on purpose," you should use わざと (wazato) or 意図的に (itoteki ni). Using 有意的 makes you sound like a philosophy textbook from the 1920s.

To truly master 有意, you must understand where it sits in the ecosystem of "meaning" and "importance" in Japanese. It is a precise tool, and sometimes you need a hammer instead of a scalpel.

有意 (Yūi) vs. 顕著 (Kencho): 有意: Mathematically significant. It might be a small difference, but it's proven.
顕著: Remarkable, striking, or obvious. Use this when a change is so big anyone can see it without a calculator (e.g., "The recovery was remarkable").
有意 (Yūi) vs. 重要 (Jūyō): 有意: Technical significance.
重要: Practical importance. A result can be statistically significant (yūi) but not important (jūyō) for the business because the effect size is tiny.
有意 (Yūi) vs. 意味深い (Imibukai): 意味深い: Deeply meaningful, profound. Use this for literature, art, or a look someone gives you. Never use 有意 for these emotional contexts.

それは統計的に有意ですが、実務上の重要性はありません。
(That is statistically significant, but it has no practical importance.)

In summary, choose 有意 when you want to sound like an expert discussing data. Choose its alternatives when you want to describe the impact or the feeling of something.

자주 묻는 질문

10 질문

No, you should use '有意義' (yūigigi) for that. '有意' is strictly for data or technical contexts.

It means 'significant difference.' It is a very common compound used in research and business reports.

Not really. You will hear it in news reports or read it in professional documents, but rarely in casual chats.

You say '統計的に有意' (tōkeiteki ni yūi).

It means 'significance level,' usually referring to the p-value (like 0.05) in statistics.

Yes, but it is a very formal or old-fashioned usage. In modern Japanese, 'itoteki' is more common for 'intentional'.

It can be both, but it's most often used as a na-adjective (有意な) or an adverb (有意に).

The technical opposite is '有意ではない' (not significant) or '偶然' (by chance).

It often refers to '有意の学習' (meaningful learning), where new info is connected to existing knowledge.

In 90% of cases, yes. It implies some kind of objective comparison or proof.
