Japanese grammar · ≈ JLPT N3 · Intermediate 3
〜きる・〜きれる~kiru / ~kireru
finish completely; be able to finish
「〜きる」 emphasizes completing an entire action, while 「〜きれる」 asks whether you can finish it all.
How it works

Reading a reference book to the last page: 「読みきる」 emphasizes completing the whole action.

Remove 「ます」 from the verb and add 「きる」: 読みます→読みきる.

「きれる」 is the potential form. It focuses on whether you can finish everything, given conditions such as time.

「きった」 means it has all been completed; 「きれない」 means you cannot complete it all.

In the example, he finishes the entire book before starting past exam questions. 「読んだ」 alone does not necessarily mean he read the whole book.

「走りきりました」 also emphasizes reaching the finish. Stopping halfway does not count as completing the run.
