Formal Ways to Say “Why Did You Do That?”
When addressing someone in a more formal setting or expressing respect, it is important to use the appropriate language and honorifics. Here are a few formal variations of the phrase:
1. なぜそれをしましたか？ (Naze sore o shimashita ka?)
The most straightforward way to ask “Why did you do that?” formally is by using this phrase. It combines the word “なぜ” (naze), meaning “why,” with “それをしましたか” (sore o shimashita ka), which translates to “did you do that?”.
Example: 社長、なぜそれをしましたか？(Shachō, naze sore o shimashita ka?) – Mr. President, why did you do that?
2. どうしてそのような行動をとられたのですか？(Dōshite sono yōna kōdō o torareta no desu ka?)
If you want to add a touch of politeness and elaborate on the person’s action, this phrase is appropriate. “どうして” (dōshite) means “why,” “そのような” (sono yōna) translates to “such,” “行動” (kōdō) means “action,” and “とられたのですか” (torareta no desu ka) indicates “did you do.”
Example: 佐藤さん、どうしてそのような行動をとられたのですか？(Satō-san, dōshite sono yōna kōdō o torareta no desu ka?) – Sato-san, why did you do such a thing?
3. 何故、そのような行為をされましたのか？(Naze, sono yōna kōi o saremashita no ka?)
For a more formal and nuanced approach, you can use this alternative. Starting with “何故” (naze), meaning “why,” it continues with “そのような行為をされましたのか” (sono yōna kōi o saremashita no ka), which translates to “did you perform such an act?”
Example: 先生、何故、そのような行為をされましたのか？(Sensei, naze, sono yōna kōi o saremashita no ka?) – Teacher, why did you perform such an act?
Informal Ways to Say “Why Did You Do That?”
When speaking in a more casual or familiar setting, using informal language can create a sense of closeness with the person you are addressing. Here are a few informal variations:
1. なんでそんなことしたの？ (Nande sonna koto shita no?)
One of the most common ways to ask “Why did you do that?” informally is using this phrase. It combines “なんで” (nande), which means “why,” with “そんなことしたの” (sonna koto shita no), meaning “did you do that?”
Example: なんでそんなことしたの？(Nande sonna koto shita no?) – Why did you do such a thing?
2. どうしてそんなことしたんだよ？ (Dōshite sonna koto shitan da yo?)
To convey a slightly more emphatic tone, this phrase can be used. It combines “どうして” (dōshite), meaning “why,” with “そんなことしたんだよ” (sonna koto shitan da yo), which translates to “did you do such a thing?”
Example: どうしてそんなことしたんだよ？(Dōshite sonna koto shitan da yo?) – Why on earth did you do such a thing?
3. なんでそんなことやったの？ (Nande sonna koto yatta no?)
This phrase, similar to the previous one, is commonly used in casual conversations among friends. “なんで” (nande) means “why,” while “そんなことやったの” (sonna koto yatta no) translates to “did you do that?”
Example: おい、なんでそんなことやったの？(Oi, nande sonna koto yatta no?) – Hey, why did you do such a thing?
