Example 4: True Innovation

これは真のイノベーションとは言えない。

Common Mistake

Confusing 相性 (aishō) and 相違 (sōi)

  • 相性 means "compatibility" (how well things work together)
  • 相違 means "difference" or "discrepancy"

Wrong: 二つのシステムの相性を確認する (when you mean "check the difference")
Correct: 二つのシステムの相違を確認する (check the difference between two systems)
Correct: ソフトとハードの相性を確認する (check the compatibility between software and hardware)
