到底

• Pinyin: dào dǐ
• Hanzi breakdown: 到 (arrive at) + 底 (bottom/end)

Meaning

After all; in the end; exactly; on earth. Used to emphasise a question or express the ultimate outcome of a situation.

In questions, 到底 adds emphasis and urgency, similar to 'on earth' or 'exactly' in English. In statements, it can mean 'in the end' or 'ultimately.' Very common in everyday speech to press for a clear answer.
