• conceptual 本词

  Describes something based on ideas or general principles rather than something already realized or built; typically used for plans, designs or artworks still at an early, unrealized stage.

  表示某事物基于概念或一般原理，而非已经实现或建成的事物；通常用于仍处于早期、尚未落实的方案、设计或艺术作品。

Both describe something that exists only as an idea, not a physical thing. Abstract means hard to picture, with no concrete form, as in abstract art. Conceptual means based on ideas or principles, still at an early, unrealized stage, like a design or plan.

这两个词都表示“只存在于观念中、而非具体实物”的抽象性质，但语气和用法略有不同：abstract 强调难以捉摸、缺乏具体形象，常形容抽象的观念、抽象艺术或抽象思维；conceptual 强调基于概念或原理，常用于尚处构思、设计阶段、还没有落实为具体成果的方案或作品。
