HSK 4
到底 Q
dàodǐ Q
in the world
Structure
Subject + 到底 + Question (Interrogative pronoun / A-not-A / 'or' choice)
How it works
The adverb '到底' (dàodǐ) is used in questions to add a sense of emphasis or urgency, similar to 'on earth' or 'in the world' in English. It indicates that the speaker is impatient or wants a definite answer to a long-standing mystery or confusion.
Examples
你到底想吃什么？
Nǐ dàodǐ xiǎng chī shénme?
What on earth do you want to eat?
这个字到底是怎么写的？
Zhège zì dàodǐ shì zěnme xiě de?
How on earth is this character written?
你到底去不去参加聚会？
Nǐ dàodǐ qù bù qù cānjiā jùhuì?
Are you going to the party or not, after all?
Common mistakes
Do not use '到底' in a simple 'yes/no' question using '吗'. It must be used with interrogative pronouns or 'A-not-A' structures.
Tip
Think of '到底' as 'getting to the bottom of the matter.' It’s most natural when someone has been hesitant or when a situation has been unclear for a while.
