I'm really sorry. It was my fault.
jeong-mal joe-song-ham-ni-da. je jal-mo-si-e-yo.
Use this in formal or polite situations when you've made a serious mistake. 정말 (really) intensifies the apology, and 제 잘못이에요 (it's my fault) takes clear responsibility.
제가 실수했어요.
I made a mistake.
je-ga sil-su-hae-sseo-yo.

용서해 주세요.
Please forgive me.
yong-seo-hae ju-se-yo.
A direct request for forgiveness. Use it when you sincerely seek the other person's pardon. It's polite and appropriate for serious apologies.
제가 책임질게요.
I will take responsibility.
je-ga chae-gim-jil-ge-yo.
Use this to promise to take responsibility for your actions, often implying you will fix the problem or compensate for it. It shows maturity and sincerity. Note: this -ㄹ게요 ending carries a promise nuance, so it sounds natural when you are reassuring the other person.

Useful pattern
The pattern '제 잘못이에요' (je jal-mo-si-e-yo) means 'It is my fault.' You can replace 제 (my) with other possessives, but for apologies, 제 is most appropriate. To emphasize, add 정말 (really) before the apology: 정말 죄송합니다. For a slightly less formal but still polite version, use 미안합니다 (mi-an-ham-ni-da) instead of 죄송합니다. However, 죄송합니다 is stronger and more sincere for serious errors. Another useful pattern is '-해 주세요' (-hae ju-se-yo), meaning 'please do ... for me,' as in 용서해 주세요 (please forgive me).
When to use it
Use these phrases when you've made a significant mistake that has caused inconvenience, harm, or hurt to someone. For example, if you forgot an important appointment, broke a promise, or caused damage, a simple 미안해 (mianhae) is too casual. Instead, say 정말 죄송합니다. 제 잘못이에요. Then, to make amends, offer a solution: 제가 책임질게요 (I will take responsibility) or 어떻게 하면 좋을까요? (What can I do to make it right?). In Korean culture, showing sincere remorse and a willingness to correct the mistake is crucial for maintaining relationships.

Yes, I waited a long time. What are you going to do?ne, ma-ni gi-da-ryeo-sseo-yo. eo-tteo-ke ha-sil geo-ye-yo?용서해 주세요. 제가 책임질게요. 다음에 꼭 지킬게요.

All right. Please contact me next time for sure.al-ge-sseo-yo. da-eum-e-neun kkok yeon-rak-hae ju-se-yo.A little context goes a long way
In Korean culture, apologies for serious mistakes often involve more than just words. Showing sincere remorse through actions, such as offering to fix the problem or giving a small gift, can help restore trust. The level of formality depends on the relationship and the severity of the error. Using formal language (죄송합니다) is safer when unsure, while casual apologies (미안해) are only for close friends or minor issues. Also, Koreans may not expect immediate forgiveness; giving the other person time to accept your apology is respectful.
One thing to watch for
Using the casual '미안해' (mianhae) for a serious mistake.
Try this instead: For serious errors, use the formal '죄송합니다' (joesonghamnida) and take responsibility with '제 잘못이에요' (je jalmosieyo). For example, say '정말 죄송합니다. 제 잘못이에요.' instead of '미안해. 내 잘못이야.'
