USAGE:
Almost exclusively used in the fixed phrase 猛威(もうい)()るう (to rage, to wreak havoc). Rarely appears outside this collocation. Subjects are typically natural disasters (台風(たいふう), 地震(じしん)), diseases (インフルエンザ, ウイルス), or other destructive forces.

COMMON COLLOCATIONS:

  • 猛威(もうい)()るう (to rage, to wreak havoc)
  • 猛威(もうい)をふるい(つづ)ける (to continue raging)
  • 自然(しぜん)猛威(もうい) (the fury of nature)

NOTE:
This word is a bound noun — it almost never appears alone without を()るう. Learning the full phrase is more useful than learning the word in isolation.
