同義詞
  • combustible

    A broader and more technical term — refers to anything that can catch fire and burn, not just things that ignite very easily

  • inflammable

    Has the exact same meaning as 'flammable' but is less common in modern safety labels because people mistakenly read it as 'not flammable'

  • ignitable

    More technical; refers specifically to the ability to catch fire rather than how fast something burns

反義詞
  • non-flammable

    The direct everyday opposite — will not catch fire under normal conditions

  • fire-resistant

    Does not burn easily but may still catch fire under extreme heat; different from fully non-flammable

  • fireproof

    Stronger than non-flammable — implies it cannot burn even under very high heat

用法筆記

Often used in safety warnings, product labels, and fire-prevention instructions. The noun it describes is the material that burns, not the source of the flame.

常見錯誤

❌The label says the liquid is inflammable, so it will not catch fire.
✅The label says the liquid is flammable, meaning it catches fire easily.
💡'Flammable' and 'inflammable' actually mean the same thing: both indicate something burns easily. The 'in-' prefix in 'inflammable' is not a negation here; it comes from Latin 'inflammare' (to set on fire).
