To Come To An End
To Be Finished, To Be Completed
intransitive verb, godan verb
Because the hiragana ends with an う sound, you know this word is a verb. The kanji itself means come to an end so the verb vocab version is to come to an end.
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you: Your romp finally has to come to an end when someone decides to sue (す) you for all your romping.
今やっと仕事が済んだところだよ。
Work just came to an end.
この作業が済んだら食堂に集まろうぜ！
Let's get together in the cafeteria once we're done with this work!
謝ったんだけど、「これは謝って済む問題じゃない」なんて言われちゃって、それで頭にきて彼の顔をひっぱたいちゃったのよね。
I apologized, but he told me apologizing wouldn't end the problem, so I got angry and slapped him in the face.
