The Literary "Also": 亦
关联副词：亦
Use 亦 to express "also" or "too" in literary, philosophical, and formal written Chinese
亦 is the classical and literary equivalent of 也 (also/too). It appears in formal essays, philosophical writing, literary prose, classical quotations, and elegant modern writing. It adds a refined, intellectual tone to any sentence.
亦 is one of the most recognizable markers of literary Chinese. It appears in many fixed expressions: 亦然 (likewise), 亦即 (that is to say), 不亦乐乎 (isn't it delightful?). In modern usage, it signals education and literary sensibility. It should never be used in casual conversation.

Understanding 关联副词：亦
The adverb 亦 is perhaps the most iconic literary adverb in Chinese. Where spoken Chinese uses 也, written and literary Chinese uses 亦 to create sentences of elegance and intellectual depth. This single character can transform an ordinary statement into something that sounds philosophical, timeless, or poetic. You will encounter 亦 constantly in classical literature, philosophical texts, formal essays, and educated modern prose. It is also preserved in numerous fixed expressions that even casual speakers know: 不亦乐乎 (from the Analerta of Confucius), 亦步亦趋 (follow someone's every step), and 人云亦云 (repeat what others say). For advanced learners, mastering 亦 means being able to read classical texts more fluently, write more polished essays, and recognize the deep connection between classical and modern Chinese.
Key Points
- 亦 means "also / too / as well" — the literary equivalent of 也.
- Belongs exclusively to written, literary, and formal Chinese.
- Appears in philosophical writing, classical quotations, and elegant modern prose.
- Common fixed expressions: 亦然, 亦即, 不亦乐乎, 亦步亦趋, 人云亦云.
- Can connect parallel ideas: "X is true; Y 亦 is true."
- Never used in casual spoken Chinese — it would sound pretentious.
The character 亦 appears in the opening passage of the Analects of Confucius (论语): 学而时习之，不亦说乎？有朋自远方来，不亦乐乎？("Is it not a pleasure to study and practice? Is it not delightful when friends come from afar?"). This makes 亦 one of the most culturally loaded characters in the Chinese language — using it evokes a literary tradition spanning over 2,500 years.
