Common patterns

  • かつて〜: former ~, ex-~ (modifies nouns directly)
  • かつて〜たことない: have never ~ed
  • かつてない: unprecedented

Nuance: かつて is more literary/formal than (むかし) or 以前(いぜん). It emphasizes the contrast between a past state and the present, and is commonly used in writing, speeches, and narration. In sense 2, it adds strong emphasis to the negation.
