同義詞
  • caster

    Variant spelling, standard in American English; refers to the same object.

  • wheel

    Much broader term — a wheel can be on a car or bicycle; a castor is specifically a small furniture wheel that usually swivels.

  • roller

    More general — can refer to paint rollers, conveyor rollers, or cylindrical objects that roll; less precise for furniture parts.

文法句型

a set of castors

castors on [furniture]

用法筆記

Usually used in the plural (castors) because furniture typically has a set of two or more. The spelling caster is common in American English and is equally correct.

常見錯誤

❌I need a castor for my new desk.
✅I need a set of castors for my new desk.
💡Castors almost always come in a set; using the singular can sound odd when referring to the furniture item as a whole.
❌The drawer slides on castor wheels.
✅The drawer slides on castors.
💡Castor wheel is redundant; castor already means a wheel for furniture.
