Nani (何): "what" in anime, and why it's sometimes nan

何

なに · nani

Nani means "what". Anime characters often shout なに!? or なにぃ!? in shock: "What?!" The kanji 何 is also often read nan, depending on the next sound.

Word by word

何なに / なんwhat

When nani becomes nan

Before sounds in the t, d and n rows or before counters, 何 usually becomes なん. Examples include 何で (nande, why), 何だ (nan da, what is it) and 何時 (nanji, what time). Alone or before particles such as を and が, it stays なに: 何を食べる?

From a question to disbelief

なに? is neutral. なんだと!? is an aggressive "What did you say?!", while なんで? means "Why?" For disbelief, there’s the very casual は?.
