How to say "something" in Japanese

Choosing the right word
  • 何かなにかJLPT N3approx.Common
    pronounThe default choice for plain indefinite 'something' — an unspecified thing, as in wanting to eat something or noticing something. It also covers 'some' and 'any'.
    ここまでのところで何なんか落おとしていることはありませんか。↗
    Have I missed anything so far?
  • なんとかJLPT N3approx.Common
    expressionVague 'something or other', used when the exact name or word escapes you or you deliberately keep things vague; it also works as a placeholder like 'so-and-so'.
  • adverbVague 'something' used when you notice or sense something but cannot tell what it is; it also renders 'some kind of', leaving the thing's nature unstated.
    私はなにやら彼かれに話はなさなければならないことがある。↗
    I have something or other to tell him.
  • 何々なになにJLPT N2approx.Common
    pronounEssentially a placeholder like 'so-and-so' or 'such and such', standing in for an unknown name or word; as 'something (or other)' it is marginal — seldom the word you want for a plain indefinite 'something'.
  • 雰囲気ふんいきJLPT N3approx.Common
    nounNot an indefinite pronoun: this noun means the air, aura or presence someone gives off, matching English only in the phrase 'there is something about her'.

Choose 「何か」 for plain indefinite 'something'; 「なんとか」 or 「なにやら」 when you speak vaguely or cannot identify the thing; 何々 mainly stands for 'so-and-so'; 雰囲気 appears only in 'a certain something about someone'.
