高潔

1. Origins, structure, and basic meaning

• Structure: 高潔 is read as こうけつ and is a な-adjectival noun for noble, upright character that is not swayed by private gain or temptation.
• Basic usage: Use 高潔な態度 before a noun and 高潔さ to name the quality itself.

2. Common pitfalls and similar expressions

• Nominalization with さ
  • 高潔さ turns the quality into an abstract noun, referring to the integrity sensed in the protagonist.
• Not social rank
  • It evaluates ethical character and resistance to profit-driven temptation, not a person’s social status.
