This is where Classical Chinese begins for almost every reader. 孔子 (Kǒngzǐ, Confucius, 551–479 BCE) taught in conversation; after his death his students collected his sayings into the 论语 (Lúnyǔ, "Analects"), and the three lines below are the book's very first passage — the opening of Book 1, 学而篇. Every educated Chinese speaker knows them by heart. They are also a perfect first taste of 文言文 (wényánwén, Classical Chinese): a written language, not a spoken one, so compressed that each character is nearly a word, and studded with grammar particles — 而, 之, 乎 — that modern Mandarin has retired from speech but never fully let go. Read this to recognize Classical grammar, not to produce it; nobody talks this way, and you shouldn't either. See spoken vs written register.
The passage
学而时习之,不亦说乎?
xué ér shí xí zhī, bú yì yuè hū?
To learn, and to practice it in due time — is that not a pleasure?
有朋自远方来,不亦乐乎?
yǒu péng zì yuǎnfāng lái, bú yì lè hū?
To have friends come from far away — is that not a joy?
人不知而不愠,不亦君子乎?
rén bù zhī ér bú yùn, bú yì jūnzǐ hū?
To go unrecognized by others, yet feel no resentment — is that not the mark of a gentleman?
Reading the lines
In full modern Mandarin, the passage expands to about twice its length:
学习知识以后,按时去温习和实践,不也是一件愉快的事吗?有志同道合的朋友从远方来看我,不也很快乐吗?别人不了解我,我却不生气、不怨恨,这不正是有修养的君子吗?
xuéxí zhīshi yǐhòu, ànshí qù wēnxí hé shíjiàn, bù yě shì yí jiàn yúkuài de shì ma? yǒu zhìtóng-dàohé de péngyou cóng yuǎnfāng lái kàn wǒ, bù yě hěn kuàilè ma? biérén bù liǎojiě wǒ, wǒ què bù shēngqì, bù yuànhèn, zhè bú zhèng shì yǒu xiūyǎng de jūnzǐ ma? (modern paraphrase)
After you've learned something, to review and put it into practice at the right times — isn't that a pleasure? To have like-minded friends come from afar to see you — isn't that a joy? When others fail to appreciate you and yet you feel no anger or resentment — isn't that exactly a person of true character?
Look at everything the paraphrase must add: 以后, 是, 一件, 的, the object 我, the whole word 生气. The Classical original states only the load-bearing characters and trusts the reader to supply the rest. The three lines also build an argument in miniature — private joy (learning), shared joy (friends), and inner strength (composure when unappreciated) — climbing from study to friendship to character. That's why it opens the book.
Grammar & classical features
而 — the all-purpose classical connective
而 (ér) links two verbs or clauses, and its exact meaning bends to context. In 学而时习之 it's sequential/additive — "learn and then practice." In 人不知而不愠 it's adversative — "unrecognized, yet not resentful." Same character, opposite flavors; you read the relationship off the sense. This one particle does the work of modern 而且, 然后, 却, and 但是 all at once. It survives in modern writing inside connectives like 然而 ("however") and 而且 ("moreover"). See 而 / 则 as classical particles.
他准备了很久,然而结果还是不太理想。
tā zhǔnbèi le hěn jiǔ, rán'ér jiéguǒ háishì bú tài lǐxiǎng
He prepared for a long time; however, the result still wasn't great. (neutral) — the classical 而 fossilized inside modern 然而.
之 — the object pronoun "it"
时习之 means "practice it" — 之 (zhī) is a Classical object pronoun standing in for what was just learned. It sits after the verb, exactly where a modern object would, but it's a bare pronoun with no antecedent spelled out. This is a different job from the attributive 之 (the literary 的 of 三分之一). Both survive in set phrases today — 求之不得 ("long for it in vain"), 取而代之 ("take its place"), 总之 ("in short, sum it up") — chunks you recognize rather than build. See 之 as a classical particle and the broader classical residue.
这个道理大家都懂,总之,做人要诚实。
zhège dàolǐ dàjiā dōu dǒng, zǒngzhī, zuòrén yào chéngshí
Everyone understands this point; in short, one should be honest. (neutral) — 之 fossilized inside modern 总之.
乎 — the classical question particle
乎 (hū) closes a question, the Classical ancestor of modern 吗 and 呢. 不亦说乎?= "is it not a pleasure?" where today you'd write 不也很快乐吗? You won't say 乎 out loud, but you'll see it in quotations, mottos, and the odd fixed phrase (如此而已乎, 何乐而不为乎). Compare the everyday 吗 yes/no question particle; 乎 is its literary predecessor, catalogued with the other classical particles.
The frame 不亦…乎 — "is it not…?"
The three lines share one skeleton: 不亦 X 乎 = "is it not X?" It's a soft, affirming rhetorical formula — the speaker is sure of the answer and invites you to agree. Slot in an adjective (说, 乐) or a noun (君子) and you get "is that not pleasant / joyful / the mark of a gentleman?" Recognizing the frame lets you parse the whole passage at a glance: three variations on one confident question.
说 read as 悦 (yuè) — the famous loan character
Here is the single most important reading trap in the passage. In 不亦说乎, the character 说 is not read shuō ("to speak"). It's read yuè, standing in for 悦 ("pleased, delighted"). In early texts 说 and 悦 were written interchangeably — a phenomenon called 通假字 (tōngjiǎzì, "loan characters"), where one character borrows another's sound and meaning. So the line means "is it not pleasing?", nothing to do with speaking. Read it shuō and the sentence collapses into nonsense. Meanwhile the next line's 乐 is read lè ("joy"), its ordinary sound.
课本上特别注明:“不亦说乎”的“说”同“悦”,是“高兴”的意思。
kèběn shàng tèbié zhùmíng: “bú yì yuè hū” de “shuō” tóng “yuè”, shì “gāoxìng” de yìsi
The textbook specifically notes: the 说 in 不亦说乎 is the same as 悦, meaning 'pleased/happy'. (neutral)
The monosyllables: 时, 习, 自, 愠, 朋
Classical Chinese is a language of one-syllable words, most of which modern Mandarin has doubled. Read the passage and watch them expand:
- 时 (shí) — "at the proper time, regularly"; modern 按时 / 时常.
- 习 (xí) — "practice, review, repeat"; modern 复习 / 练习 / 温习. Alive in 学习, 习惯.
- 自 (zì) — "from"; modern 从. 自远方来 = 从远方来. Alive in 来自, 自从.
- 愠 (yùn) — "resentful, sullenly angry"; modern 生气 / 怨恨. Nearly dead outside this passage.
- 朋 (péng) — "friend"; modern 朋友.
These literary/everyday swaps are the same register machinery mapped on the content-word pairs page. And 君子 (jūnzǐ) — the "gentleman," a person of moral cultivation — is the central Confucian ideal, defined throughout the Analects against its opposite, 小人 (xiǎorén, "petty person").
不亦乐乎 survives as a modern idiom
Best of all, the passage's second line lives on. 不亦乐乎 broke off from the Analects and became a stock modern idiom meaning "to the extreme, like crazy, no end of it" — usually after a verb + 得. 玩得不亦乐乎 = "having an absolute blast"; 忙得不亦乐乎 = "busy as anything." Most speakers use it without ever thinking of Confucius, which is exactly how deep classical residue runs in the living language. It's earned a place among the everyday set phrases.
孩子们在雪地里玩得不亦乐乎,谁也不肯回家。
háizimen zài xuědì lǐ wán de bú yì lè hū, shéi yě bù kěn huí jiā
The kids were having the time of their lives in the snow — none of them would go home. (informal) — the Analects line reborn as an everyday idiom.

Key Takeaways
- This is 文言文 (Classical Chinese) — written, never spoken. Read it to recognize the grammar; don't build sentences with it.
- 而 links clauses with a context-dependent sense: "and then" (学而时习) or "yet" (不知而不愠).
- 之 is the object pronoun "it" (习之 = "practice it"); 乎 is the classical question particle, ancestor of 吗.
- 不亦…乎 is a rhetorical frame — "is it not…?" — a confident, affirming near-exclamation, not a real question.
- 说 here is read yuè (= 悦, "pleased"), a 通假字 loan — never shuō; the next line's 乐 is lè ("joy").
- Classical monosyllables expand in modern Mandarin: 时→按时, 习→复习, 自→从, 朋→朋友 — and 不亦乐乎 survives today as an idiom for "like crazy."
