Formation
Meaning
To do something completely to the end, or to do something with great intensity/conviction.
Note
Indicates that an action is performed thoroughly and completely (finish reading a book, run to the end) or with extreme intensity (completely exhausted, fully convinced). When used with '〜きれる' (potential form), it emphasizes the ability to complete the entire amount or action. It suggests a clear 'endpoint' or 'limit' has been reached.
