Chinese Attitude Adverbs — 居然/竟然/果然/其实

Attitude adverbs (语气副词 yǔqì fùcí) express the attitude, judgment, surprise, or expectation of the speaker toward a statement. They do not describe how much or how often something happens; instead they color the whole sentence with a subjective take.

The four core attitude adverbs here are 居然 (unexpected surprise), 竟然 (stronger, more formal surprise), 果然 (expectation confirmed), and 其实 (correcting a wrong assumption). All four sit before the main verb or adjective, and often before 是/会/能.

居然 jūrán marks something that happened or is true against expectation, and carries surprise. 他居然忘了我的名字 — "he actually forgot my name." 这个菜居然这么好吃 — "this dish is unexpectedly so delicious."

It works for both pleasant and unpleasant surprise: 你居然来了 ("you actually came" — a pleasant surprise), 他居然迟到了 ("he actually was late").

Position: before the verb or adjective, or before 是/会: 他居然会说法语 ("he can actually speak French"), 居然是他 ("it is actually him"). It often pairs with 没想到 (did not expect): 没想到他居然同意了 ("I did not expect he would actually agree").

竟然 jìngrán is a near-synonym of 居然, but slightly stronger and more written or formal. 他竟然不辞而别 — "he actually left without saying goodbye." 我竟然考了满分 — "I actually got full marks."

竟然 tends to emphasize shock that reality went beyond expectation or should not have happened, so it is more emphatic than 居然. It also fits 敢/能/会: 你竟然敢骗我 — "you even dare to lie to me."

居然 vs 竟然: 居然 is the neutral, everyday choice and slightly colloquial; 竟然 is stronger and more formal or written. They are often interchangeable, but 竟然 carries more astonishment or disapproval.

果然 guǒrán marks that a prediction or expectation came true. 天气预报说会下雨，果然下了 — "the forecast said it would rain, and sure enough it did."

他果然来了 ("he came, as expected"), 果然是他 ("sure enough, it is him"). 果然不出所料 means "as expected, no surprise."

Contrast with 居然/竟然: 居然/竟然 = reality OPPOSED the expectation (surprise), while 果然 = reality MATCHED the expectation (confirmation). 他果然来了 ("I expected him to come, and he did") vs 他居然来了 ("I did not expect him, and he did").

其实 qíshí corrects a mistaken assumption or reveals the truth. 你以为他很穷，其实他很有钱 — "you think he is poor, actually he is rich."

其实我不喜欢咖啡 ("actually I do not like coffee"), 大家都以为他走了，其实他还在 ("everyone thought he left, actually he is still here").

其实 can lead the sentence or sit after the subject: 他其实并不想去 ("he actually does not want to go"). 其实 is everyday; 实际上 is the more formal, written equivalent.

Do not use 其实 to mean "very" or "really" as an intensifier — that job belongs to 真的 or 确实 (真的很难 = really hard), not 其实.

All four sit before the main verb or adjective and can come before 是/会/能/敢: 居然是 / 竟然是 / 果然是 / 其实是.

They can often stand right after the subject or at the very start: 其实我不喜欢咖啡 vs 我其实不喜欢咖啡.

They are subjective: they express the attitude of the speaker rather than an objective fact, so they are natural in speech and narrative, but out of place in neutral reports.

Do not confuse 果然 (expected) with 居然/竟然 (unexpected). 他果然来了 = he came as expected; 他居然来了 = he came unexpectedly.

Do not use 其实 as an intensifier meaning "very". Say 真的很难 or 确实很难 for "really hard", not 其实很难.

Do not overuse 竟然 in casual speech — it is formal and strong; 居然 is the neutral everyday choice.

Do not use 居然/竟然 when nothing is surprising. 他居然来了 implies you did not expect him; if his arrival was expected, say 他果然来了.

Do not use 果然 without a prior expectation or prediction — it needs a forecast to confirm.
