任何【rènhé】

任何 + noun means "any" – every one of them, without exception. When the 任何 phrase comes before the verb, 都 or 也 follows it.

With a negative, 任何 is "not any, none at all". After 没有 or a negated verb, it sits in the object, and no 都 is needed.

Time and place

任何时候 "any time" and 任何地方 "anywhere" work the same way, before the verb with 都.

Where it goes wrong

A 任何 phrase before the verb needs 都 or 也. Without it, the sentence feels cut off.

• × 任何人知道这件事 → 任何人都知道这件事
• × 任何地方没有 → 任何地方都没有

任何 is "any at all". For "any" in an ordinary question, Chinese usually needs no word at all, or 什么.

• × 你有任何咖啡吗？ → 你有咖啡吗？
