to finish doing ~
🏁 verb stem + 終わる (owaru, to end) = finish doing: 読み終わる, finish reading
終わる is the plain verb for to end. Attach it to a verb's masu-stem and it marks that action as completed: 食べ終わる = finish eating, 書き終わる = finish writing. Sound hook: owaru starts like over, and the action is over.
