Meaning (意思 yìsi)

到底 is used in questions to emphasize the inquiry, meaning "in the end," "after all," or "exactly/just."

Explanation (解释 jiěshì)

Adverb 到底 (dàodǐ) is used in questions for emphasis, pressing to the bottom of an issue. It expresses impatience, uncertainty, or a desire for a final, definitive answer. In English it corresponds to 'after all', 'in the end', 'just exactly', or 'on earth' (as in "What on earth do you mean?"). Use 到底 when you have run out of patience and want to get to the truth.
