一点儿 / 有点儿

yìdiǎnr / yǒudiǎnr a little

Both translate as "a little," and learners mix them up constantly. The rule is simple once you see it: 有点儿 goes before an adjective and leans negative, while 一点儿 goes after and stays neutral.

有点儿 yǒudiǎnr and 一点儿 yìdiǎnr both come out as "a little" in English, which is why they are one of the most reliably confused pairs in beginner Mandarin. But they sit in different positions and carry different feelings, and once you fix those two facts, they stop being confusing.

有点儿 comes before an adjective and usually expresses a mild complaint or an undesirable state: 有点儿贵 ("a bit too expensive"). 一点儿 comes after an adjective and is neutral, typically comparative: 贵一点儿 ("a little more expensive"). The position alone is a near-perfect guide: if the "a little" sits before the adjective, it must be 有点儿; if it sits after, it must be 一点儿. They are not interchangeable in slot or in tone.

The decisive contrast 有点儿 + Adjective , 有点儿贵 · a bit (too) expensive , a complaint
Adjective + 一点儿 , 贵一点儿 · a little more expensive , neutral / comparison
Verb + 一点儿 + (Noun) , 喝一点儿水 · drink a little water
Wrong: 一点儿贵 · 一点儿 cannot precede the adjective
有点儿 yǒudiǎnr 有点儿 + Adjective — A Bit Too…
有点儿 yǒudiǎnr a bit; somewhat (often "a bit too…")
ADV 副词 fùcí
Placed before an adjective (or a feeling-verb) to say something is "a bit / somewhat" that way, usually with a tinge of complaint or an unwanted state. 有点儿 + 累 / 冷 / 贵 / 难 = a bit tired / cold / expensive / hard. It describes a current condition the speaker finds slightly undesirable. Often written 有点 without 儿 in the south and in writing.
我今天有点儿累。
Wǒ jīntiān yǒudiǎnr lèi.
I'm a bit tired today.
这件衣服有点儿贵。
Zhè jiàn yīfu yǒudiǎnr guì.
This piece of clothing is a bit (too) expensive.
这个问题有点儿难。
Zhège wèntí yǒudiǎnr nán.
This question is a little hard.
语法 yǔfǎ · Grammar Because 有点儿 carries a faintly negative flavour, it pairs naturally with undesirable adjectives (累, 贵, 难, 麻烦). Using it with a positive one (有点儿好) sounds odd unless there is an implied "but." To say simply "very," use ; 有点儿 is specifically "a bit too much for comfort."
一点儿 yìdiǎnr Adjective/Verb + 一点儿 — A Little (More)
一点儿 yìdiǎnr a little; a bit (neutral, often comparative)
QUANT 数量 shùliàng
After an adjective, 一点儿 makes a neutral comparison, "a little more X": 大一点儿 (a bit bigger), 快一点儿 (a bit faster), 便宜一点儿 (a little cheaper). After a verb, it means "a little / some": 喝一点儿水 (drink a little water), 说一点儿 (say a bit). It often implies adjusting toward a preferred amount, with none of the complaint of 有点儿.
请说慢一点儿。
Qǐng shuō màn yìdiǎnr.
Please speak a little slower.
能不能便宜一点儿?
Néng bu néng piányi yìdiǎnr?
Could it be a little cheaper?
我会说一点儿中文
Wǒ huì shuō yìdiǎnr Zhōngwén.
I can speak a little Chinese.
语法 yǔfǎ · Grammar In requests, adjective + 一点儿 is the polite way to ask for an adjustment: 大一点儿 (a bit bigger), 慢一点儿 (a bit slower). The 一 is often dropped after a verb in fast speech, leaving 点儿: 喝点儿水. Note 差一点儿 is a fixed phrase meaning "almost / nearly," a separate idiom worth learning on its own.
辨析 biànxī Side by Side — The Decisive Test
辨析 biànxī · The Quick Rule

Compare the same adjective in both frames. 这个有点儿贵 = "this is a bit too expensive" (a complaint about the current price). 这个贵一点儿 = "this one is a little more expensive" (a neutral comparison with something else). The position of "a little" relative to the adjective changes both the structure and the meaning, and English flattens the difference into one word.

So the test has two steps. First, position: before the adjective it must be 有点儿; after it must be 一点儿. Second, feeling: 有点儿 reports an undesirable state ("a bit too…"), while 一点儿 makes a plain comparison or asks for an adjustment ("a little more…"). If you want to grumble that something is a touch too expensive, 有点儿贵; if you want to ask for it a little cheaper, 便宜一点儿. Keeping the two slots and the two tones apart resolves the whole confusion.

常见问题chángjiàn wèntíFrequently Asked Questions
What is the difference between 一点儿 and 有点儿?
有点儿 yǒudiǎnr comes before an adjective and usually carries a slightly negative feeling, 'a bit too…': 有点儿贵 ('a bit (too) expensive'). 一点儿 yìdiǎnr comes after an adjective (or verb) and is neutral, often comparative, 'a little (more)': 便宜一点儿 ('a little cheaper'). The position is the quickest test: 有点儿 + adjective, but adjective + 一点儿.
When do you use 有点儿?
Use 有点儿 (or 有点) before an adjective to say something is 'a bit too' that quality, usually with a complaining or undesirable tone: 有点儿累 ('a bit tired'), 有点儿冷 ('a bit (too) cold'), 这个菜有点儿辣 ('this dish is a little too spicy'). It expresses a mild negative reaction to a current state. You generally do not use it before a positive adjective like 好 unless implying a hidden 'but'.
When do you use 一点儿?
Use 一点儿 after an adjective for comparison ('a little more X'): 大一点儿 ('a little bigger'), 快一点儿 ('a bit faster'). Use it after a verb to mean 'a little / a bit (of)': 喝一点儿水 ('drink a little water'), 我会说一点儿中文 ('I can speak a little Chinese'). In northern speech the 儿 is added; elsewhere 一点 / 有点 without 儿 is common.
Can you say 一点儿贵 to mean 'a little expensive'?
No, that word order is wrong. To say something is 'a bit (too) expensive' as a current state, use 有点儿贵 (有点儿 before the adjective). To say 'a little more expensive' as a comparison, use 贵一点儿 (一点儿 after the adjective). 一点儿 cannot sit before the adjective the way 有点儿 does; this is the core error the pair is famous for.
