最
zuì
Superlative "zui"
最 is the superlative — the most, the -est.
最 + Adj. (+ 了)
How it works
最好, 最贵, 最喜欢. It sits directly in front of the adjective or the verb of preference.
Unlike English, no article or "of all" is needed: 谁最有钱? — who's the richest?
最 also attaches to verbs of liking: 我最喜欢中国菜.
Examples
shéi zuì yǒu qián?
谁最有钱？
Who's the richest?
wǒ zuì xǐ huan zhōng guó cài
我最喜欢中国菜。
Chinese food is my favourite.
zhè shì zuì hǎo de bàn fǎ
这是最好的办法。
This is the best way.
