You might say, 'I have confidence in my teacher,' which means you trust your teacher to help you. It is a simple but very important word for how we feel when we try new things.

At the A2 level, 'confidence' means you believe in your abilities. You use this word to describe how you feel about your skills, like speaking, writing, or playing a sport.

At the B1 level, 'confidence' is the feeling of being certain about your own abilities or the truth of something. It is also about trust. You can use it in many situations, like at work or school.

'I am telling you this in confidence' means 'Please don't tell anyone else.' It is a very common word in daily life and helps you describe your feelings and your relationships with others more clearly.

At the B2 level, 'confidence' involves a deeper sense of self-assurance and reliability. It is often used in professional contexts, such as 'consumer confidence' or 'investor confidence,' which refer to how people feel about the economy. You understand that confidence can be 'shaken' by bad news or 'boosted' by success. You also know that 'confidence' can be used as an adjective in 'confidence trick' (a scam).

confidence 30秒で

Confidence is a noun meaning self-assurance in one's abilities or trust in others. It is essential for personal growth and successful social interactions.
The word can also mean a secret or private information shared with trust. Phrases like 'in confidence' highlight this specific usage in daily life.
In business and politics, confidence refers to the level of trust or optimism in a system, leader, or the economy, affecting stability and growth.
Grammatically, it is often paired with the preposition 'in' and verbs like 'boost', 'gain', or 'shake'. It is distinct from the adjective 'confident'.

The word confidence is a multifaceted noun that primarily describes a state of being certain. At its core, it is the psychological assurance in one's own powers, abilities, or judgment. When a person possesses confidence, they approach tasks with a sense of readiness and a lack of debilitating doubt. This is not merely about being 'right,' but about the belief that one can handle the outcome, whether successful or not. In social contexts, confidence manifests as a calm demeanor and the ability to express thoughts clearly without excessive anxiety. It is the fuel for leadership and the foundation of personal growth. Beyond the self, confidence also extends to the trust we place in others. When you have confidence in a friend, you rely on their integrity and consistency. In the world of finance, 'consumer confidence' measures how optimistic people are about the economy, which directly influences spending habits. This word is ubiquitous in self-help literature, professional coaching, and everyday conversations about performance and relationships. It is a bridge between potential and action, allowing individuals to step out of their comfort zones. Understanding confidence requires looking at it as both an internal feeling and an external projection. It is often the difference between a person who hesitates and a person who executes a plan. However, it is important to distinguish it from arrogance; true confidence is rooted in reality and competence, whereas arrogance is often a mask for insecurity. In academic settings, confidence intervals in statistics provide a range of values within which we can be certain a parameter lies, showing that the word also has a precise, technical application in science and mathematics.

Self-Assurance: The internal belief that one is capable of achieving a goal or performing a task effectively.

Trust in Others: The reliance on the character, ability, strength, or truth of someone or something else.

Confidentiality: A state of trust where information is shared with the expectation that it will not be disclosed to others.

The young athlete played with such confidence that the scouts immediately took notice of his potential.

I am telling you this in strict confidence, so please do not repeat it to anyone else in the office.

Building confidence in public speaking requires hours of practice and positive reinforcement from mentors.

Using the word confidence correctly involves understanding its grammatical collocations and the various contexts in which it appears. As a noun, it often follows verbs like 'gain,' 'lose,' 'build,' 'boost,' or 'restore.' For example, 'She gained confidence after passing her driving test.' Here, the word describes an increase in self-assurance. It can also be used with prepositions, most commonly 'in.' You have confidence in something or someone. 'I have full confidence in your ability to lead this project.' This indicates a high level of trust. Another common structure is 'in confidence,' which means privately or secretly. 'He told me the news in confidence.' In this case, it functions as an adverbial phrase describing the manner of sharing information. When discussing the level of confidence, we use adjectives like 'shaken,' 'unwavering,' 'growing,' or 'supreme.' 'His unwavering confidence inspired the entire team to keep trying.' The word can also act as an adjective in specific compound nouns like 'confidence trick' or 'confidence man' (con man), where it refers to exploiting someone's trust for fraudulent purposes. In formal writing, you might see 'lack of confidence,' which is a polite way to say someone is unsure or incompetent. 'The board expressed a lack of confidence in the current management.' This is a very strong statement in a corporate environment. Furthermore, the word appears in the phrase 'vote of confidence,' which is a formal expression of support. 'The manager gave the new employee a vote of confidence by assigning her a major client.' By mastering these patterns, you can use 'confidence' to describe everything from personal feelings to complex social and professional dynamics. It is a versatile tool for expressing the degree of certainty or trust present in any given situation.

Verb + Confidence: Common verbs include: gain, lose, build, boost, restore, shake, inspire, and betray.

Adjective + Confidence: Common adjectives include: absolute, full, supreme, quiet, growing, shaken, and low.

Prepositional Phrases: Common phrases include: in confidence, with confidence, lack of confidence, and confidence in.

You should speak with confidence if you want the audience to believe your message.

In the real world, confidence is a buzzword across many domains. In the professional sphere, you will hear it during performance reviews, where managers might discuss an employee's 'growing confidence' in their role. In business news, economists frequently discuss 'consumer confidence' or 'investor confidence' as key indicators of economic health. If these levels are high, it suggests that people are willing to spend and invest, which drives growth. In the realm of sports, commentators often attribute a player's success to their 'confidence on the field,' noting how a single successful play can transform their entire performance. In social settings, friends might encourage each other by saying, 'You just need a bit more confidence!' or 'Don't let that mistake knock your confidence.' In the legal and medical professions, 'confidence' is often synonymous with 'privacy' or 'confidentiality.' A doctor might say, 'Everything we discuss is in the strictest confidence,' meaning it is legally and ethically protected from being shared. You will also encounter the word in the context of 'confidence intervals' if you study statistics or read scientific papers, where it describes the reliability of data. In politics, a 'vote of no confidence' is a formal procedure used to show that a leader is no longer supported by their governing body. This wide range of usage—from the deeply personal to the highly technical—makes 'confidence' one of the most important words to master for effective communication in English. It bridges the gap between how we feel about ourselves and how we interact with the systems and people around us.

Business & Economics: Terms like 'consumer confidence index' and 'market confidence' are used to describe economic stability.

Politics: A 'motion of no confidence' can lead to the resignation of a government or prime minister.

The central bank raised interest rates to restore confidence in the national currency.

The therapist worked with the patient to rebuild her confidence after a traumatic event.

One of the most frequent mistakes learners make is confusing the noun confidence with the adjective confident. Remember: 'I have confidence' (noun) but 'I am confident' (adjective). You cannot say 'I am confidence' or 'I have confident.' Another common error involves the preposition used after the word. While 'confidence in' is the standard for trust in someone or something, learners sometimes mistakenly use 'of' or 'on.' For example, 'I have confidence on him' is incorrect; it should be 'I have confidence in him.' Additionally, the phrase 'in confidence' is sometimes misused. It means 'secretly,' but some learners use it to mean 'with self-assurance.' If you want to say someone spoke with self-assurance, say 'He spoke with confidence.' If he told you a secret, he told you 'in confidence.' There is also a subtle confusion between 'confidence' and 'confidentiality.' While related, 'confidence' is the state of trust, whereas 'confidentiality' is the formal principle or set of rules protecting private information. In a professional setting, saying 'I will keep this in confidence' is more personal, while 'I will maintain confidentiality' sounds more like a legal obligation. Finally, be careful with the word 'overconfidence.' While confidence is generally positive, 'overconfidence' implies a lack of realism and can lead to mistakes. Learners often use 'high confidence' when they actually mean 'overconfidence' in a negative context. Understanding these nuances will help you avoid sounding unnatural and ensure your meaning is clear to native speakers.

Noun vs. Adjective: Wrong: He is very confidence. Correct: He is very confident. / He has a lot of confidence.

Preposition Error: Wrong: Confidence of the future. Correct: Confidence in the future.

Many students confuse confidence with arrogance, but they are very different traits.

While confidence is a powerful word, there are several synonyms and alternatives that can provide more specific meaning depending on the context. Self-esteem is often used interchangeably with confidence, but it refers more to one's overall sense of self-worth rather than the belief in specific abilities. Assurance or self-assurance suggests a calm, certain manner, often in social or professional situations. Poise refers to a graceful and elegant bearing, often maintained under pressure. In a more technical or formal sense, reliance or trust can replace confidence when talking about our belief in others. For example, 'I have full reliance on their expertise.' If you want to describe a very high level of confidence that might be seen as negative, words like hubris or presumption are used. On the positive side, conviction describes a very strong, firm belief in something, often a moral or political principle. 'She spoke with the conviction of someone who truly believed in the cause.' Certainty is a more direct synonym for the state of being sure. 'There is a growing certainty that the project will succeed.' By choosing the right alternative, you can add nuance to your writing and speaking, making your descriptions of human emotion and social trust much more precise.

Confidence vs. Self-Esteem: Confidence is about 'doing' and 'ability'; self-esteem is about 'being' and 'worth'.

Confidence vs. Conviction: Confidence is a feeling of ability; conviction is a deeply held belief or principle.

His assurance in the boardroom made everyone feel that the company was in safe hands.
