Emphasis with "jiushi"

As an adverb, 就 (jiù) can be placed before the predicate to add emphasis. It often has an intense or provocative feel to it, similar to "just." It's just like how we sometimes say in English, "it's just not right!" This emphasis very often appears as 就是.

Used as "Is Exactly"

Structure

就是 + Noun

Examples

• 那个 人 就是 她 的 新 男朋友。Nàge rén jiùshì tā de xīn nánpéngyou.That guy is her new boyfriend.
• 他 就是 你 要 找 的 人 。Tā jiùshì nǐ yào zhǎo de rén.He's just the person that you're looking for.

Used as "only Because"

就是 can be used to intensify the predicate to mean "only (because of) that and nothing else." In this case, 是 can't be omitted. In many cases, you could also add in an 因为, but it's not required.

Examples

Other Usage

In the examples above, 就 pairs exclusively with the verb 是. But 就 can also come before other verbs, with similar emphatic effect. In these cases, it's also OK to use 就是 before the other verbs as well.

Structure

就(是) + (不) + Verb

Examples

• 我 就 要 去！Wǒ jiù yào qù! I just want to go!
• 我 就是 喜欢 他。Wǒ jiù shì xǐhuan tā.I just like him.
• 我 就 不 告诉 你 。Wǒ jiù bù gàosu nǐ.I'm just not going to tell you.
• 我 父母 就是 不 让 我 一个人 去 。 Wǒ fùmǔ jiùshì bù ràng wǒ yīgèrén qù.My parents simply won't let me go alone.
• 这个 学生 就是不 听 老师 的 话 。Zhège xuéshēng jiùshì bù tīng lǎoshī de huà.The student just wouldn't listen to his teacher.

As you may have noticed, many of these uses of 就 or 就是 carry a flippant, stubborn tone, referred to as 任性 (rènxìng) in Chinese.
