What does 一点儿 mean?
一点儿 (yìdiǎnr) means 'a little / a bit / a small amount' — used to soften a request, downplay a quantity, or describe a slight degree. Two patterns are essential. First, after a verb: 我会说一点儿中文 'I can speak a little Chinese,' 请等一点儿 'please wait a bit.' Second, after an adjective with a comparative feel: 便宜一点儿 'a bit cheaper,' 大一点儿 'slightly bigger.' Important contrast: 一点儿 vs 有一点儿 (yǒu yīdiǎnr). 有一点儿 + adjective means 'somewhat / a bit (and usually negative)': 有一点儿贵 'a bit expensive (and I'm not happy about it).' Plain 一点儿 after the adjective is a comparative: 贵一点儿 'a bit more expensive (than something else).' These two are commonly mixed up. In Beijing speech the 儿 is fully pronounced; elsewhere it disappears.
Note: The 儿 (er-suffix) is a Northern Mandarin / Beijing feature. In Taiwan, southern Mainland speech, and formal writing it's dropped: 一点 (yìdiǎn). Both forms mean the same thing; learners can use either.
Character breakdown
one
dot; point; small amount
diminutive er-suffix (often unwritten in pinyin as 'r')
Memory hook: 一 (one) + 点 (dot) + 儿 (small-suffix) = 'one little dot' = a little bit. Literal and tidy.

Common phrases with 一点儿
Synonyms
一些 means 'some / several' — a vaguer plural quantity that works with countable nouns: 一些朋友 'some friends.' 一点儿 is smaller and works with mass nouns and degrees: 一点儿水 'a little water.' You wouldn't say 一点儿朋友.
稍微 ('slightly') is an adverb meaning 'a bit' before adjectives or verbs — more formal/written. 稍微大一点儿 'slightly bigger.' 一点儿 is the spoken everyday version.
Don't confuse 一点儿 with
有一点儿 goes BEFORE adjectives and usually carries a negative tone: 这个有一点儿贵 'this is a bit (too) expensive.' Plain 一点儿 goes AFTER adjectives for neutral comparison: 这个贵一点儿 'this is a bit more expensive (than that one).' Order matters.
一下 means 'briefly / for a moment' (a TIME concept): 等一下 'wait a moment.' 一点儿 is about AMOUNT or DEGREE. They're not interchangeable: 喝一下 'drink briefly' vs 喝一点儿 'drink a little.'
