Class Notes: Deep Dive into the Chinese Character 是 (shì)
Objective
Learn the full range of usages of the Chinese character 是 (shì), a crucial "glue" word essential for fluency, including its role across contrasts, affirmations, emphasis, alternatives, and hypotheticals.
I. Introduction
是 (shì): Essential character in Mandarin for affirming, contrasting, comparing, and adding emphasis.
Mastery helps you sound more fluent and understand natural Chinese better.
II. The Basics: 是 as "To Be"
Noun = Noun construction: Subject + 是 + Identity
Examples:
他是医生。= He is a doctor.
妈妈是我妈妈。= Mom is my mom.
我们是情侣。= We are a couple.
我是美国人。= I am an American.
Note: 不 use 是 for adjectives/descriptions:
WRONG: 他是胖。
RIGHT: 他很胖。
III. Related Basic Usages
是的 (shì de): Yes, that’s right/correct.
不是 (bù shì): No, isn't/not.
也是 (yě shì): Also is (i.e., me too).
总是 (zǒng shì): Always is/always.
只是 (zhǐ shì): Only/just (used for emphasis or limitation).
都是 (dōu shì): All are/both are (covers both "all" and "both").
IV. Formal and Moral Usage
是否 (shì fǒu): Whether or not (formal, used for hypotheticals).
Example: 他是否值得信任?(Is he trustworthy or not?)
是非 (shì fēi): Right and wrong (moral judgment).
V. 是 in Correction, Affirmation, and Emphasis
At sentence end: soft affirmation, seeking agreement (right?).
As sarcastic/snarky "Really?" when used alone as an exclamation.
Difference in tone: 是吧 (not so sure), 是吗 (50/50 not sure), 是 (pretty sure).
VI. Contrasts and "But" Conjunctions
但是 (dàn shì) / 可是 (kě shì): But, however.
Extremely common in both spoken and written Chinese.
若果A,但是B。(If A, but B.)
但是 is more formal than 可是.
而是 (ér shì): Not this, but (rather) that.
Structure: 不是A,而是B = Not A, but rather B.
Example: 不是我不想去,而是我今天有事。("It's not that I don't want to go, but I have things to do today.")
VII. Providing Options and Making Choices
还是 (hái shì): Or (for questions/hypotheticals, presenting alternatives).
A 还是 B ? (Coffee or tea?)
Use 或 (huò) for "or" in statements, not questions.
Choice Example: 今天我们吃中国菜还是汉堡?(Are we eating Chinese food or hamburgers tonight?)
VIII. Emphasizing Details with 是 … 的 Structure
Used to emphasize time, location, person, method in the past or to stress specific details.
Structure: 是 + (detail to emphasize) + 的
Examples:
是昨天晚上妈妈回家的。("It was last night that mom came home.")
我是1987年在香港当司机的。("It was in 1987 that I was a driver in Hong Kong.")
这本书是玛丽的。("This book belongs to Mary.")
Moving 是 … 的 focuses emphasis on different parts of the sentence.
IX. Hypotheticals: "Even If" with 就是 … 也 (jiù shì … yě)
Structure: 就是 + hypothetical + 也 + action = Even if (hypothetical), still (action).
Example: 就是失败了, 也要继续努力。("Even if I fail, I'll still keep trying.")
Used for expressing resilience, persistence despite circumstances.
X. Key Takeaways

Basic identity statements
Affirmation and negation
