Meaning and Usage
"到底" (とうてい) is an adverb used to express that something is absolutely impossible or cannot be done no matter what. It often appears in negative sentences to emphasize the impossibility or strong denial.
Common Contexts
It is frequently used in formal or written Japanese, especially in situations where the speaker wants to stress that something cannot be accepted, believed, or achieved under any circumstances.
Collocations and Patterns
- "到底 + negative verb" (e.g., 信じられない, 解決できない): emphasizes impossibility.
- Often used with verbs like 納得する (to agree), 信じる (to believe), 解決する (to solve).
Register and Nuance
This word is more formal and literary than casual expressions like ぜったいに (definitely). It conveys a strong sense of impossibility or denial.
Common Mistake
Learners sometimes confuse "到底" with "結局" (けっきょく, after all) because both can appear in questions or statements about outcomes. Remember, "到底" stresses impossibility, while "結局" indicates a final result or conclusion.
