飛び散る

1. Origins, structure, and basic meaning

• Structure: The written form is 飛び散る, read とびちる. Elements for flying and scattering combine in an intransitive verb for droplets, sparks, or similar matter dispersing in many directions.
• Basic usage: 油が飛び散る states that oil actually splattered, while 火花が飛び散らない uses a negative form for the aim of preventing sparks from scattering.

2. Common pitfalls and similar expressions

• Scattering after a cause
  • After water falls into hot oil, the oil itself scatters in droplets. Example: 熱い油に水滴が落ちて、油が飛び散った。 — A drop of water fell into the hot oil and made it splatter.
• Negative form for prevention
  • The cover is attached so that sparks do not spread outward during cutting. Example: 切断中に火花が飛び散らないよう覆いを付けた。 — We attached a cover to prevent sparks from scattering during cutting.
