Pratique Exemplos Notas e dicas 強さ em 30 segundos
Explicação 強さ in your Level:
At the A1 level, '強さ' (tsuyosa) is introduced as the noun form of '強い' (tsuyoi - strong). You can think of it as 'how strong something is.' It is most commonly used to talk about the weather or simple physical things. For example, 'The wind's strength' (kaze no tsuyosa). At this stage, you don't need to worry about complex abstract meanings. Just remember that adding '-sa' to the end of an adjective makes it a noun, like 'strength' or 'height.' If you want to ask 'How strong is the wind?', you can use 'tsuyosa.' It's a useful word for basic descriptions of the world around you.

At the A2 level, you start using '強さ' (tsuyosa) to describe people and their abilities in a simple way. You might hear it in sports or games. For example, 'I was surprised by his strength' (kare no tsuyosa ni odorokimashita). You are also learning to distinguish it from the word 'chikara' (power). Remember: 'chikara' is the thing you have, while 'tsuyosa' is the quality of being strong. You can use it to talk about the intensity of light or heat as well. It helps you add more detail to your sentences by turning adjectives into nouns that can be the focus of your thought.

At the B1 level, '強さ' (tsuyosa) becomes more abstract. You will use it to discuss 'mental strength' (seishinteki na tsuyosa) and character. This is a key level for understanding the nuance of the '-sa' suffix. You should be able to use it in more complex sentence structures, such as 'The secret to their strength is teamwork' (karera no tsuyosa no himitsu wa chimuwaku desu). You will also encounter it in news reports about the economy or social issues. At this stage, you should start noticing how it differs from 'tsuyomi' (a specific advantage or strong point).
At the B2 level, you are expected to use '強さ' (tsuyosa) in professional and academic contexts. You might discuss the 'strength of a brand' or the 'structural strength' of a building. You should understand how it collocates with various verbs like 'hokoru' (to boast) or 'iji suru' (to maintain). You will also see it used in literature to describe the intensity of emotions or the force of an argument. At this level, you should be comfortable using 'tsuyosa' to quantify abstract concepts like 'the strength of a relationship' or 'the strength of a conviction.'

At the C1 level, '強さ' (tsuyosa) is used to analyze subtle nuances in discourse. You will distinguish between 'tsuyosa' (inherent strength), 'iryoku' (coercive power), and 'kyōdo' (technical intensity). You might use it in social critiques, such as discussing the 'strength of social norms' or the 'inherent strength of a democratic system.' You should be able to appreciate the philosophical implications of 'tsuyosa' in Japanese culture, such as the relationship between strength and vulnerability. Your usage should be precise, choosing 'tsuyosa' only when you specifically mean the degree or quality of being strong.

At the C2 level, '強さ' (tsuyosa) is a tool for sophisticated expression. You can use it to discuss the 'ontological strength' of an idea or the 'rhetorical strength' of a speech. You understand its historical and cultural baggage, including its use in martial arts philosophy (Budō). You can use it in highly formal writing, such as legal or scientific papers, where it might refer to the 'probative strength' of evidence. At this level, you are not just using the word; you are manipulating its connotations to convey deep, layered meanings about power, resilience, and the nature of reality.

強さ em 30 segundos

  • Tsuyosa means 'strength' or 'intensity' and is the noun form of the adjective 'tsuyoi'.
  • It is used for physical power, mental resilience, weather force, and abstract concepts like brand strength.
  • The suffix '-sa' indicates that it is a measurable degree or state of being strong.
  • It differs from 'chikara' (power as a resource) and 'tsuyomi' (a specific advantage).

The Japanese word 強さ (tsuyosa) is a foundational noun derived from the i-adjective 強い (tsuyoi), meaning 'strong.' In Japanese grammar, the suffix -sa is added to the stem of adjectives to transform them into nouns that represent a measurable degree, state, or quality. Therefore, tsuyosa translates to 'strength,' 'power,' 'intensity,' or 'force' depending on the context. It is a versatile term that spans the physical, emotional, and abstract realms. Whether you are discussing the physical power of an athlete, the intensity of a storm, or the resilience of a person's character, tsuyosa is the go-to term.

Physical Magnitude
This refers to the literal force exerted by an object or person. It is used for muscle power, the structural integrity of materials, or the force of natural phenomena like wind and waves.
Emotional Resilience
In a psychological context, it describes 'mental strength' (精神的な強さ). It is the ability to withstand stress, overcome adversity, and remain steadfast in one's beliefs.
Intensity of Sensation
It can describe the brightness of light, the heat of a fire, or the pungency of a smell. It measures the degree to which a stimulus affects the senses.
「彼の本当の強さは、筋肉ではなく心にある。」
(His true strength lies not in his muscles, but in his heart.)

Understanding tsuyosa requires recognizing that it is not just a binary state (strong vs. weak) but a spectrum. When you use the -sa suffix, you are often inviting a comparison or a measurement. For example, 'the strength of the wind' (風の強さ) implies a scale from a light breeze to a hurricane. This distinguishes it from the suffix -mi, which would imply a more subjective, internal quality (though tsuyomi exists, it specifically refers to 'a strong point' or 'advantage' rather than the general concept of strength).

「風の強さを測る装置が必要です。」
(We need a device to measure the strength of the wind.)
Competitive Dominance
In sports or games like Go and Shogi, it refers to the skill level or the winning capability of a player or team.
「このチームの強さの秘密は何ですか？」
(What is the secret to this team's strength?)

Using 強さ (tsuyosa) effectively involves understanding its grammatical role as a noun. Because it is a noun, it can be the subject of a sentence, the object of a verb, or modified by other nouns and adjectives. It frequently appears in the pattern [Noun] + の + 強さ to specify what kind of strength is being discussed.

1. As a Subject or Object

You can use it with particles like は (wa), が (ga), or を (o). For instance, to say 'The strength is surprising,' you use 強さが驚くべきだ. To say 'I admire her strength,' you use 彼女の強さを尊敬する.

「光の強さを調節してください。」

(Please adjust the intensity of the light.)

2. Comparing Levels

Since tsuyosa represents a degree, it is often used with verbs of comparison like 競う (kisou - to compete) or 比べる (kuraberu - to compare). In sports commentary, you will hear people comparing the 'strength' of different eras or champions.

強さを誇る (tsuyosa o hokoru)
To boast of one's strength/power.
強さを身につける (tsuyosa o mi ni tsukeru)
To acquire strength (often mental or skill-based).

3. Abstract vs. Concrete

When using tsuyosa for abstract concepts, it often pairs with words like 精神的 (seishinteki - mental) or 組織的 (soshikiteki - organizational). For concrete things, it pairs with physical properties like 粘着 (nenchaku - adhesion) or 結合 (ketsugo - bonding).

「精神的な強さが試される場面だ。」

(This is a situation where mental strength is tested.)

The word 強さ (tsuyosa) is ubiquitous in Japanese society, appearing in diverse settings from weather forecasts to philosophical discussions. Its frequency in media makes it an essential word for B1 learners to master.

1. Weather and Nature

Meteorologists use tsuyosa constantly. You will hear it in phrases like 'the strength of the wind' (風の強さ) or 'the intensity of the rain' (雨の強さ). During typhoon season, the tsuyosa of the storm determines the warning levels issued to the public.

「台風の強さは、中心気圧で判断されます。」

(The strength of a typhoon is judged by its central barometric pressure.)

2. Sports and Competition

Whether it's Sumo, Baseball, or E-sports, commentators discuss the tsuyosa of athletes. It refers to their physical power, their winning streak, or their 'clutch' ability under pressure. In Shogi (Japanese chess), it refers to the depth of a player's strategic calculation.

3. Pop Culture (Anime and Manga)

Shonen manga is obsessed with tsuyosa. Characters often go on journeys to find 'true strength.' The dialogue frequently revolves around measuring power levels or questioning what it means to be strong. Themes of 'inner strength' (心の強さ) are central to many narratives.

「お前の強さの源は何だ？」

(What is the source of your strength?)

4. Business and Marketing

Companies discuss the 'strength of the brand' (ブランドの強さ) or the 'strength of the economy' (景気の強さ). In marketing, the tsuyosa of a message refers to its impact and how well it resonates with the target audience.

While 強さ (tsuyosa) is a straightforward noun, learners often trip up on its nuances compared to similar words or its grammatical application.

1. Confusing 'Tsuyosa' with 'Chikara' (力)
This is the most common error. 力 (chikara) usually refers to 'power,' 'ability,' or 'force' as an entity or a resource you possess. 強さ (tsuyosa) is the degree or quality of being strong.

Incorrect: 腕の強さを使ってドアを開ける (Using the 'strength' of the arm to open the door).
Correct: 腕の力を使ってドアを開ける (Using the power/force of the arm).
2. Confusing 'Tsuyosa' with 'Tsuyomi' (強み)
As mentioned before, tsuyomi is a 'strong point' or 'advantage.' If you say 'My tsuyosa is English,' it sounds like you are measuring the physical force of your English.

Incorrect: 私の強さは英語です。
Correct: 私の強みは英語です。
3. Overusing it for 'Intensity' of Emotions
While tsuyosa can mean intensity, for emotions like 'love' or 'hatred,' Japanese often uses 深さ (fukasa - depth) or 激しさ (hagishisa - violence/intensity) instead.

Natural: 愛の深さ (Depth of love) vs. Unnatural: 愛の強さ (Strength of love - though sometimes used, 'depth' is more common).

To truly master 強さ (tsuyosa), you should understand the words that live in its neighborhood. Japanese has many specific terms for different types of 'strength.'

威力 (iryoku)
Refers to 'might' or 'power,' often used for weapons, storms, or the influence of an authority. It implies a destructive or overwhelming force.
強度 (kyōdo)
A technical term for 'strength' or 'intensity.' Used in engineering (tensile strength) or physics (light intensity). It is more formal and objective than tsuyosa.
権力 (kenryoku)
Political or social power. This is the 'strength' someone has because of their position in a hierarchy.
頑丈さ (ganjō-sa)
Sturdiness or robustness. Used for furniture, buildings, or a person's physical build. It emphasizes durability.

Subjective/General

強さ (Tsuyosa)

General degree of strength.

Technical/Objective

強度 (Kyōdo)

Measured physical intensity.

When choosing between these, ask yourself: Am I measuring a quality (tsuyosa), describing a technical specification (kyōdo), or talking about the power to influence others (kenryoku)?
