Let’s look at some examples!

Part 1: Casual Suggestions

1. なんてことをするの？ (Nante koto o suru no?) – “How could you do such a thing?”

This is a softer way to express shock or disappointment, perfect for casual situations.

“なんて” (nante) means “such” or “what kind of,” “こと” (koto) means “thing,” “を” (o) marks the object, and “する” (suru) means “to do.”

Adding “の” (no) at the end turns it into a question, making it sound like “How could you do such a thing?”

It’s less aggressive but still clearly shows your feelings.

This phrase works well with friends when you’re teasing or mildly upset.

Try pairing it with a playful tone for a lighthearted effect.

2. よくもそんなことが言えるね！ (Yokumo sonna koto ga ieru ne!) – “How dare you say something like that!”

This phrase is stronger and directly challenges what the other person said.

“よくも” (yokumo) means “how dare,” “そんなこと” (sonna koto) means “such a thing,” “が” (ga) marks the subject, and “言える” (ieru) is “can say.”

The “ね” (ne) at the end softens it slightly, like seeking agreement or emphasizing disbelief.
