每…都 (every ... all) — Chinese grammar (HSK 2)

每 + Measure word / Time word + (Noun) + 都 + Verb

每 (měi) means "every" and is followed by a measure word or a time unit: 每个人, 每年, 每天, 每个星期. Chinese almost always adds 都 (all) before the verb to reinforce it, even though English says only "every". Think of 每…都 as a fixed pair.

Examples

我每个星期都去游泳。 Wǒ měi ge xīngqī dōu qù yóuyǒng.	I go swimming every week.
每个人都喜欢她。 Měi ge rén dōu xǐhuan tā.	Everyone likes her.
她每年都去中国。 Tā měi nián dōu qù Zhōngguó.	She goes to China every year.

Tip: Leaving out 都 is the most common slip; 每个人喜欢她 sounds unfinished.
