Let the describing word do the predicate’s work
English commonly links a subject to an adjective with a form of “be.” Mandarin does not ordinarily need 是 in the corresponding plain description. 忙 describes being busy, 累 describes being tired, and 贵 describes being expensive. These words can do the central predicate work themselves. Textbooks may call them adjectives or stative verbs. The terminology differs, but the useful beginner behavior is the same: do not insert an identity verb automatically before them.
Compare 她是老师 with 她很忙. The first identifies her occupation using a noun. The second describes her condition. Both translate into English with “she is,” but their Mandarin predicates are built differently. This is why translating the English linking verb one word at a time creates avoidable errors. Choose the kind of message first, then the Mandarin pattern that carries it.
This lesson concerns ordinary descriptive statements. 是 can appear with adjectives in marked constructions, including certain emphatic or contrastive contexts. That fact does not make it the default link for every description, and beginners do not need to learn those more specialized patterns to describe a friend or a book accurately. Establish the plain pattern first. Later exceptions will be easier to understand if you know which ordinary pattern they modify.
她是老师。
Tā shì lǎoshī.
She is a teacher.
她很忙。
Tā hěn máng.
She is busy.
我很累。
Wǒ hěn lèi.
I am tired.
Build an ordinary description
Say simply that she is tired.
- The message describes a condition, not a noun identity.
- Use 累 as the predicate and 很 for the ordinary positive pattern.
- Do not insert 是 to match English “is.”
她很累。
Understand what 很 contributes
The familiar dictionary translation of 很 is “very.” That is useful, but it does not explain every ordinary sentence containing the word. In a neutral positive adjective predicate, unstressed 很 often helps present the description without an implied contrast. 我很忙 can simply mean that I am busy. Translating every occurrence as “extremely busy” would exaggerate what the speaker necessarily claims.
At the same time, do not conclude that 很 has no meaning in every situation. Context and emphasis can give it a clearer degree meaning. A speaker who stresses it, or contrasts a stronger and weaker description, may genuinely be communicating a high degree. The lesson’s English translations use natural wording for the stated situation rather than assigning one unchanging intensity to every written 很. A translation is an interpretation of the whole message, not a code that mechanically replaces each character.
For your first neutral affirmative statements, subject plus 很 plus adjective is a dependable starting pattern. You can describe yourself, a known person or an identified object. The adjective does not change for singular versus plural subjects or for the person speaking. That stability lets you focus on the predicate choice and context. It does not mean that every adjective construction elsewhere in Mandarin must contain 很.
我很忙。
Wǒ hěn máng.
I am busy.
这本书很贵。
Zhè běn shū hěn guì.
This book is expensive.
他们很累。
Tāmen hěn lèi.
They are tired.
Distinguish “not” from “not very”
For a basic negative description, put 不 before the adjective. 我不忙 says that I am not busy, and 这本书不贵 says that this book is not expensive. You do not need to retain 很 merely because the positive model contained it. Negative grammar is not always formed by placing a new word in front of an otherwise untouched positive sentence.
The ordering of degree and negation affects meaning. 不很忙 can mean “not very busy,” which is weaker than directly saying “not busy.” Another common expression is 不太忙, also “not very busy” or “not particularly busy.” Someone who is not very busy may still have a little work. In a real conversation that difference can matter: you are qualifying the degree, rather than denying busyness altogether.
For this beginner lesson, keep the simplest distinction clear before exploring more emphatic combinations. 不贵 and 不太贵 are not interchangeable answers to a prompt that explicitly contrasts “not expensive” with “not very expensive.” They can both be appropriate in some real situations, but they state different levels of commitment. The exercises specify the intended meaning so that the grammar choice reflects a real distinction instead of an arbitrary preference for one grammatical sentence.
我不忙。
Wǒ bù máng.
I am not busy.
我不太忙。
Wǒ bù tài máng.
I am not very busy.
这本书不贵。
Zhè běn shū bù guì.
This book is not expensive.
Ask about the description directly
To ask an ordinary question about a description, you can place 吗 at the end. 你忙吗 asks whether the listener is busy. 很 is not required in this basic question. If you instead ask 你很忙吗, the question can concern being very busy or check a description already under discussion. Both forms can occur, but they do not justify a rule that every question must preserve the neutral positive statement’s 很.
Another common pattern places the adjective on both sides of 不: 忙不忙, 贵不贵, or 累不累. This presents the positive and negative possibilities inside the predicate. In the ordinary pattern taught here, do not also append 吗. Choose one question construction. Combining the two markers is not how to make the question more polite or more emphatic in this beginner structure.
A reply can repeat the adjective or its negative when the subject is obvious. To 你累吗, 累 or 不累 directly answers the relevant description. A fuller answer such as 我很累 is also useful, especially when you want to continue with an explanation. Do not reach automatically for 是 or 不是 merely because the English question begins with “are.” Match the Mandarin predicate that was actually asked about.
你忙吗?
Nǐ máng ma?
Are you busy?
这本书贵不贵?
Zhè běn shū guì bù guì?
Is this book expensive?
不累。
Bù lèi.
Not tired.
Separate a description from a describing noun phrase
An adjective predicate makes a statement about a subject. A describing phrase inside a noun phrase helps identify or characterize the noun itself. Compare 这本书很贵, “this book is expensive,” with 很贵的书, “an expensive book” or “books that are expensive,” depending on context. In the second expression, 的 connects the description to the following noun. That phrase alone does not make the same complete statement as the first sentence.
This distinction matters when you build a larger message. 我有一本很贵的书 says that you have an expensive book. The main predicate is 有, while 很贵的 describes the book inside its object phrase. You cannot decide where 的 belongs merely by looking for an adjective somewhere in the sentence. Identify whether the adjective is making the sentence’s central assertion or modifying a noun within it.
Not every familiar adjective and noun combination uses 的. 新书 is a common expression for a new book, and short established combinations deserve to be learned as useful units. Do not turn that observation into permission to remove 的 from any longer descriptive phrase. For new beginner combinations with 很 plus an adjective before a noun, keeping 的 provides a clear and productive model. Other modifier patterns can be learned individually as your vocabulary grows.
很贵的书
hěn guì de shū
an expensive book; expensive books
我有一本很贵的书。
Wǒ yǒu yī běn hěn guì de shū.
I have an expensive book.
新书
xīn shū
a new book; new books
Turn a statement into a noun description
Compare “this book is expensive” with “an expensive book.”
- The statement places the known book first, followed by 很贵.
- The noun phrase puts the description before 书 and connects it with 的.
- A noun phrase can become part of a larger sentence, but it is not automatically a complete assertion.
Compare your reasoning
这本书很贵。 / 很贵的书
Use time and contrast without changing the adjective
A description can be limited to a particular time. 我今天很忙 says that the speaker is busy today. 我昨天不忙 describes yesterday differently. The adjective itself does not gain an English style past ending. Time words and the surrounding conversation establish when the description applies. This is another reason to resist a mechanical translation built around English “was” or “were.”
An explicit contrast can also make a bare adjective natural. In 我今天忙,明天不忙, the speaker contrasts today with tomorrow. The first 忙 need not carry 很 because the parallel contrast gives it a clear role. Bare adjectives also occur in answers and other grammatical environments. Therefore “always add 很 before an adjective” is too broad, even though 很 is an excellent starting point for an ordinary neutral affirmative statement.
Keep the difference between a description and an identity visible as you add detail. A person can be a teacher and tired today; one predicate identifies an occupation, while the other reports a state. You can connect such information through separate clear sentences before trying longer constructions. Accuracy here comes from making the time and the kind of predicate explicit, not from memorizing a separate adjective form for each tense or each person.
我今天很忙。
Wǒ jīntiān hěn máng.
I am busy today.
我昨天不忙。
Wǒ zuótiān bù máng.
I was not busy yesterday.
我今天忙,明天不忙。
Wǒ jīntiān máng, míngtiān bù máng.
I am busy today, but not tomorrow.
Describe what matters in the situation
Choose an adjective that evaluates the relevant quality. 贵 concerns price; it does not automatically mean that a book is difficult. 好 is broad and depends on the thing being discussed. 好喝 specifically evaluates something as pleasant to drink, while 好吃 evaluates food as pleasant to eat. Learning these useful words prevents you from expecting one English adjective such as “good” to cover every Mandarin expression in exactly the same way.
A practical conversation often moves from a question to an evaluation and then to a decision. You can ask whether a book is expensive, answer that it is not very expensive, and say that it is good. The grammar stays simple while the context supplies what “good” means. Do not turn a short phrase into a universal judgment about a language, country or group of people. The examples concern a particular object or the speaker’s current experience.
Before opening the questions, describe one identified object and your present condition. Then make one description negative and turn the other into a question. Finally, contrast the complete sentence with a noun phrase containing 的. These small transformations test different grammatical decisions. They are more informative than copying the same positive model repeatedly, because they show whether you understand why 很, 不, 吗 and 的 appear in their particular positions.
这杯茶很好喝。
Zhè bēi chá hěn hǎohē.
This cup of tea tastes good.
这个菜很好吃。
Zhè ge cài hěn hǎochī.
This dish tastes good.
这本书很好。
Zhè běn shū hěn hǎo.
This book is good.
Notice the difference
Common mistakes
Do not copy the English linking verb
Instead of我很是累。
For this meaning我很累。
The ordinary adjective predicate does not need 是, and 很 belongs before the describing word.
Keep one ordinary question construction
Instead of你忙不忙吗?
For this meaning你忙不忙?
The positive and negative question pattern already marks the alternatives. Do not append 吗 in this basic construction.
Link a longer noun modifier
Instead of很贵书
For this meaning很贵的书
The descriptive phrase 很贵 modifies the following noun through 的.
Do not erase the degree distinction
Instead of我不忙。
For this meaning我不太忙。
If you mean “not very busy,” 不太 preserves that weaker degree claim. The first sentence is grammatical but directly denies busyness.
From understanding to using
Make your own example.
Try these without answer choices. Say your answer aloud or write it below, then compare your reasoning with the model.
Your turn 1
Say that you are tired today and are not busy.
Compare with a model
我今天很累。我不忙。 (Wǒ jīntiān hěn lèi. Wǒ bù máng.)
I am tired today. I am not busy.
The positive description uses 很. The basic negative uses 不 directly before the adjective.
- Place 今天 before the adjective predicate.
- Do not add 是 to either plain description.
Your turn 2
Ask whether this book is expensive using 吗, then answer “not very expensive.”
Compare with a model
这本书贵吗?不太贵。 (Zhè běn shū guì ma? Bù tài guì.)
Is this book expensive? Not very expensive.
The basic question does not require 很. 不太 qualifies the degree, allowing some expense.
- Keep the classifier 本 with 这 and 书.
- Distinguish not very expensive from a direct denial of being expensive.
Put it into practice
Make the next choice.
Choose a response and learn why it works. Your score reflects your first answer to each question. You can revisit anything you miss.
Choose an answer, then open the explanation to check your reasoning.
Question 1
Choose the ordinary statement “She is tired.”
- 她很累。
- 她很是累。
Check the answer
Answer: 她很累。
她很累。: Correct. The adjective supplies the description without 是.
她很是累。: This is not the plain adjective pattern requested here.
Question 2
Which sentence identifies an occupation rather than describing a condition?
- 她很忙。
- 她是老师。
Check the answer
Answer: 她是老师。
她很忙。: This describes busyness rather than identifying an occupation.
她是老师。: Correct. 老师 is a noun identity.
Question 3
Must unstressed 很 in every ordinary positive statement mean an extreme degree?
- No
- Yes
Check the answer
Answer: No
No: Correct. It often supports a neutral description, while context and emphasis can supply degree.
Yes: That would overstate what many ordinary descriptions necessarily mean.
Question 4
Choose the basic “I am not busy.”
- 我没有老师。
- 我不忙。
Check the answer
Answer: 我不忙。
我没有老师。: This means that you do not have a teacher, not that you are not busy.
我不忙。: Correct. 不 directly negates the adjective.
Question 5
You have some work, but are not very busy. Which explicitly gives that weaker degree?
- 我不太忙。
- 我不忙。
Check the answer
Answer: 我不太忙。
我不太忙。: Correct. 不太 means not very or not particularly.
我不忙。: This directly denies being busy rather than explicitly qualifying the degree.
Question 6
Choose an ordinary question about whether the listener is tired.
- 你是累吗?
- 你累吗?
Check the answer
Answer: 你累吗?
你是累吗?: This is not the ordinary plain question pattern being practiced.
你累吗?: Correct. The basic adjective question can omit 很.
Question 7
Choose the ordinary positive and negative question form.
- 你忙不忙?
- 你忙不忙吗?
Check the answer
Answer: 你忙不忙?
你忙不忙?: Correct. The predicate presents both alternatives.
你忙不忙吗?: Do not combine this basic pattern with 吗.
Question 8
A friend asks 你累吗. You are not tired. Reply:
- 没有。
- 不累。
Check the answer
Answer: 不累。
没有。: That would normally answer a possession or availability question, not this description.
不累。: Correct. This directly denies the adjective predicate.
Question 9
Which is a describing noun phrase, rather than the statement “this book is expensive”?
- 很贵的书
- 这本书很贵。
Check the answer
Answer: 很贵的书
很贵的书: Correct. 的 connects the description to the noun.
这本书很贵。: This is a complete description of an identified book.
Question 10
Complete the longer modifier in “I have an expensive book.”
- 我有一本很贵书。
- 我有一本很贵的书。
Check the answer
Answer: 我有一本很贵的书。
我有一本很贵书。: This longer description needs 的 in the taught pattern.
我有一本很贵的书。: Correct. 很贵的 describes 书 inside the object phrase.
Question 11
Does the common expression 新书 prove that every longer adjective phrase can omit 的?
- No
- Yes
Check the answer
Answer: No
No: Correct. Learn common short combinations without extending their pattern to every modifier.
Yes: That would incorrectly remove 的 from productive phrases such as 很贵的书.
Question 12
In the explicit contrast 我今天忙,明天不忙, must the first adjective add 很?
- Yes
- No
Check the answer
Answer: No
Yes: The neutral positive starting pattern is not a universal requirement in contrasts.
No: Correct. The parallel contrast provides the setting for the bare adjective.
Question 13
Which adjective most directly evaluates the taste of a drink?
- 好喝
- 贵
Check the answer
Answer: 好喝
好喝: Correct. This is used for something pleasant to drink.
贵: This evaluates expense rather than taste.
Question 14
To describe yesterday’s lack of busyness, choose:
- 我昨天没有车。
- 我昨天不忙。
Check the answer
Answer: 我昨天不忙。
我昨天没有车。: This denies having a car yesterday, not being busy.
我昨天不忙。: Correct. The time expression gives the past setting; the adjective has no past ending.
