USAGE:
刹那(せつな) is literary and dramatic. It typically appears in the pattern その刹那(せつな) (at that very instant) or ~の刹那(せつな) (at the moment of ~). Not used in everyday casual conversation — 瞬間(しゅんかん) is the neutral equivalent.

COMMON PATTERNS:

  • その刹那(せつな) (at that very instant)
  • ~した刹那(せつな) (the moment ~ happened)
  • (いっ)(しゅん)刹那(せつな) (a fleeting instant)

SIMILAR WORDS:
瞬間(しゅんかん) (moment/instant) is the standard, neutral word for a brief moment. 刹那(せつな) is more literary and carries a sense of dramatic tension. 刹那(せつな)(てき) (momentary, living for the moment) is a common derivative.
