Translation

抽象的な / 具体物ではない / 概念上の

Meaning

Abstract means about ideas, qualities, or relationships rather than concrete things you can touch. It is common in academic writing, philosophy, art, and business discussion. The trap is using abstract when you simply mean vague.

Examples

• 正義は抽象的な考えなので、例があると説明しやすくなります。
  Justice is an abstract idea, so examples make it easier to explain.
• 彼女の発表は少し抽象的すぎて、具体的な数字が必要でした。
  Her presentation was a little too abstract and needed concrete numbers.
