USAGE:
Functions as a na-adjective (稀有(けう)な). This is a formal, literary word — in everyday conversation, (めずら)しい is far more common. 稀有(けう) is chosen when the speaker wants to emphasize how truly exceptional something is.

COMMON COLLOCATIONS:

  • 稀有(けう)才能(さいのう): rare talent
  • 稀有(けう)存在(そんざい): a rare existence

READING NOTE:
Also sometimes read きゆう, but けう is the standard modern reading.

SIMILAR WORDS:
(めずら)しい is the everyday word for "rare" or "unusual." 稀有(けう) is more elevated and emphasizes extraordinary rarity. 希少(きしょう) means "scarce" and is used more for resources, species, and quantities.
