How to say "commonly" in Japanese

• 俗にぞくにCommon
  adverbCovers 'commonly' only in the sense of 'commonly called or said': it introduces a popular or colloquial name or expression. Typical context: noting what something is popularly called, as opposed to its formal name.
• 一般にいっぱんにCommon
  adverbUse this when 'commonly' means 'generally' or 'widely': it frames a statement as true of people or things at large, rather than describing a popular name or an ordinary state of affairs.
  この単語たんごは、一般いっぱんによく使つかわれていない。↗

  This word is not in common use.
• 普通ふつうJLPT N4approx.Common
  adverbHere 'commonly' amounts to 'usually' or 'normally': use it for what ordinarily happens or is the case. It does not cover popular names or expressions, and is a looser match for plain 'commonly'.
  彼女かのじょは普通ふつう９時じに寝ねる。↗

  She usually goes to bed at nine.

Choose 「俗に」 for what people commonly call or say, 「一般に」 for statements that hold generally or widely, and 普通 for what normally or usually happens; 普通 is the loosest fit for 'commonly' itself.
