Use 是 to identify people and things
是 shì is commonly translated as “to be,” but its most useful beginner role is linking one noun to another. 我是老师 wǒ shì lǎoshī means I am a teacher. 他是医生 tā shì yīshēng means he is a doctor. 这是书 zhè shì shū means this is a book.
The form 是 does not change. English uses am, is, and are, while Mandarin keeps 是 after singular and plural subjects. This is why one pattern can produce many useful sentences.
- 我是学生。Wǒ shì xuésheng. — I am a student.
- 你是老师。Nǐ shì lǎoshī. — You are a teacher.
- 他们是朋友。Tāmen shì péngyou. — They are friends.
- 那是我的车。Nà shì wǒ de chē. — That is my car.
Build the sentence in three parts
A basic identity sentence has a subject, 是, and a noun description. Start with the person or thing, add 是, and finish with the identity, nationality, profession, or relationship.
In the pattern 我是巴基斯坦人 wǒ shì Bājīsītǎn rén, 我 is the subject, 是 is the linking verb, and 巴基斯坦人 means Pakistani person. Replace the final noun to say student, teacher, doctor, businessperson, or friend.
- Subject + 是 + profession
- Subject + 是 + nationality
- Subject + 是 + relationship
- 这 or 那 + 是 + object
Do not use 是 before every adjective
A common beginner mistake is translating every English “is” with 是. In a simple description, Mandarin normally uses an adjective as the predicate, often with 很 hěn. 她很好 tā hěn hǎo means she is well or good. The natural sentence is not 她是很好.
Use 是 when the second part identifies or classifies the subject. Use an adjective pattern when the second part describes a quality. Compare 他是老师, he is a teacher, with 他很好, he is well or good.
- Correct: 他是医生。— He is a doctor.
- Correct: 他很好。— He is well.
- Correct: 这本书很好。— This book is good.
- Avoid inserting 是 only because English contains “is.”
Make a negative sentence with 不是
Place 不 bù directly before 是 to form 不是 bú shì, is not or am not. Before a fourth-tone syllable such as shì, 不 changes from fourth tone bù to second tone bú in normal pronunciation.
The word order remains stable: subject + 不是 + noun. 我不是医生 wǒ bú shì yīshēng means I am not a doctor. 那不是我的书 nà bú shì wǒ de shū means that is not my book.
- 我不是老师。— I am not a teacher.
- 他不是中国人。— He is not Chinese.
- 这不是我的车。— This is not my car.
- 他们不是学生。— They are not students.
Short practice from the course pattern
Translate each idea by keeping the same three-part structure. Say your answer before checking it. Then make a negative version with 不是.
This controlled substitution method comes from Abdul Azeem’s original beginner course. It helps learners produce a pattern repeatedly before moving to freer conversation.
- I am Pakistani.
- You are my friend.
- She is a Chinese teacher.
- That is a book.
- We are not doctors.
- This is not his house.
