About
The word 到底 is formed by combining the character 到, meaning "to arrive" or "to reach", with 底, meaning "bottom" or "base", resulting in a literal sense of "to reach the bottom". This literal composition then gives rise to figurative meanings, such as carrying something through to the end or emphasizing a final point, which underlie its modern uses as an adverb expressing "after all", "finally", or "on earth" in questions.
