既 (jì)…又 (yòu)… Structure in Chinese Grammar: The Quick Guide

Just as 又 (yòu)…又 (yòu)… is used in spoken Chinese, 既 (jì)…又 (yòu)… is a more formal way of expressing that two qualities or situations coexist. Depending on what comes after it in the sentence, the structure can mean “both A and B” or “both do A and do B”.
In this article, we’ll first explain the two uses of 既 (jì)…又 (yòu)… in Chinese with examples, and then, we’ll take a look at its variation.
Let’s get right on it.
Expressing “both A and B” with 既 (jì)…又 (yòu)…
You can use 既 (jì)…又 (yòu)… with adjectives in Chinese to attribute multiple qualities to something. It’s like saying that something is “both adj 1 and adj 2” in English.
Pattern
(subject) + 既 (jì) adjective 1 + 又 (yòu) adjective 2
* the subject can be omitted if it’s self-evident from the context.
In most cases, the two adjectives used after 又 (yòu) need to have the same connotations. That is, they should both be positive or negative as a pair, and can’t contradict each other. For instance, you can use the pattern to say things like “she’s both pretty and smart”, but not “she’s both pretty and dumb”.
Let’s look at some examples:
Positive pair

Línjū de xiǎohái jì cōngmíng yòu kě’ài.

Expressing “both do A and do B” with 既 (jì)…又 (yòu)…
You can also use 既 (jì)…又 (yòu)… in conjunction with verb phrases to express “both do A and do B”.
Pattern
(subject) + 既 (jì) verb phrase 1 + 又 (yòu) verb phrase 2

Zàixiàn xuéxiào jì ràng jiāzhǎng fàngxīn, yòu shǐ xuéshēng mǎnyì.

既 (jì)…又 (yòu)… can also be used with verb phrases in the negative. Simply translate the structure as “neither…nor…” in this case.
- 她既不会唱歌又不会跳舞。
Tā jì bú huì chànggē yòu bú huì tiàowǔ.

(he is both not willing to go to school and not willing to work)
It’s worth pointing out that, most of the time, verb phrase 1 and verb phrase 2 will be built on the same main verb (i.e. 既是 jì shì….又是 yòu shì…) or a similar one (i.e, 既让 jì ràng…又使…yòu shǐ). This has little to do with grammar, but rather a language habit. It’s a common practice that native speakers pair up the verb phrases in the 既 (jì)…又 (yòu)… structure to make it sound more natural.
既 (jì)…又 (yòu)… VS 又 (yòu)…又 (yòu)…
The expression 既 (jì)…又 (yòu)… is quite formal. You are encouraged to use it when you write articles or give a speech in Chinese. In daily conversation, however, you might want to use 又 (yòu)…又 (yòu)… instead. It works the same, but conveys a much more relaxed, casual tone.
邻居的小孩既聪明又可爱。Línjū de xiǎohái jì cōngmíng yòu kě’ài.
→ 邻居的小孩又聪明又可爱。Línjū de xiǎohái yòu cōngmíng yòu kě’ài.
