What does “I'm (so) sorry” mean?

"I'm sorry" is used to apologize. It is also used to show sympathy or regret. "I'm so sorry" is stronger and more emotional.

When people say it

For your mistake or bad reaction: "I'm sorry. I overreacted."
In service situations before you help: "I'm so sorry. I'll fix that right away."
When plans change or you cannot go: "Something came up. I'm so sorry."
To show sympathy after bad news: "I'm so sorry to hear that."

Tone: It is natural and common in casual and polite speech. "I'm so sorry" sounds stronger, but it does not always mean a very serious mistake.
