How to say "universally" in Japanese

• 一般にいっぱんにCommon
  adverbIt is the common, default choice when 'universally' means 'generally, as commonly held or done' — general prevalence among people at large, rather than literal coverage of every case.
  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.
• あまねく
  adverbFits 'universally' as 'everywhere, far and wide' — something spreading to or holding in all places. Less common, and usually written in kana alone; not the word for 'generally accepted' statements.
• 広くひろく
  adverbLess common: really the adverb 'widely', it fits 'universally' when that means 'by many people, over a broad range', as in widely known or accepted; stronger 'every case' senses are a stretch.

Choose 「一般に」 for the 'generally, commonly accepted' sense of 'universally', 「あまねく」 for sweeping 'everywhere, far and wide' coverage, and 「広く」 when 'universally' really just means 'widely'.
