How to say "anybody" in Japanese

• 誰でもだれでもCommon
  expression, pronounCovers 'anybody/anyone' in the sense 'no matter who', and by extension 'everyone/everybody'. The direct equivalent when 'anybody' stands on its own, as in saying that anyone at all may join.
  サムは彼かれの援助えんじょを求もとめる人ひとなら誰だれでも援助えんじょする。↗

  Sam helps whoever asks him to.
• 誰にでもだれにでもCommon
  expression, conjunctionAlso matches 'anybody', but its built-in に presents the person as the one affected or addressed — 'to/for anyone'. It suits talk of how one treats people, such as being kind to anyone; also glossed 'whoever'.
  １度いちどや２度どの失敗しっぱいはだれにでもある。↗

  Everybody fails once or twice.

Use 「誰でも」 for plain 'anybody/anyone' — 'no matter who', also 'everyone' — and 「誰にでも」 when the statement is directed at the person, 'to/for anybody', as its built-in に shows.
