てでも

てでも is used to emphasize that you are willing to do something or endure a situation no matter what happens next. It conveys strong determination or willingness to take drastic steps to achieve a goal, often in situations where success is uncertain or difficult. It is stronger and more forceful than the typical 〜ても. Note that with verbs you use the て-form and add でも; with nouns or na-adjectives you use でも after the noun/na-adjective form (e.g., N でも, Na-adjective stem + でも). Typical contexts include pursuing a goal at any cost, refusing to give up in the face of obstacles, or deciding to take an extreme action to ensure an outcome.
