什么都 / 谁都 / 哪儿都【shénme dōu / shéi dōu / nǎr dōu】

A question word with 都 after it stops asking and means "every": 什么都 "everything", 谁都 "everyone", 哪儿都 "everywhere". Put 不 or 没 after 都 and it means "none": nothing, nobody, nowhere.

The question word goes before the verb

However the English is worded, 什么 and 哪儿 move in front of the verb, and 都 follows them.

• × 我都吃什么 → 我什么都吃
• × 我不知道什么都 → 我什么都不知道
• × 我不想去哪儿 → 我哪儿都不想去

也 in negatives

With a negative, 也 is as common as 都.

With a noun

什么 or 哪 + measure word can carry a noun along: 什么东西, 哪个人, 哪本书.

怎么都 and 什么时候都 follow the same pattern: "no matter how", "any time".
