殊勝

1. Origins, structure, and basic meaning

• Structure: 殊勝 (しゅしょう) is a descriptive expression that evaluates conduct or attitude as admirable. 殊勝な modifies a noun, whereas 殊勝だ completes a judgment.
• Basic usage: 殊勝な心掛け modifies the attitude shown by voluntary cleaning; 殊勝だと思った embeds an assessment prompted by the boy's apology.

2. Common pitfalls and similar expressions

• Attributive な and predicative だ
  • 殊勝な is followed by the evaluated noun 心掛け, while 殊勝だ is followed by と思った, which reports the judgment. The two forms should not both be read as ordinary prenominal “admirable.”
