煞费苦心

1. Basic Information

• Pinyin: shà fèi kǔ xīn
• English Translation: To take great pains (racking one's brains)
• Idiom Composition: 「煞」（Extremely or very (used here as an intensifier for the degree of effort).）＋「费」（To spend, consume, or use up (referring to the expenditure of energy or resources).）＋「苦」（Painstaking, bitter, or hard (representing the difficulty or hardship involved).）＋「心」（Heart or mind (the seat of thought, intention, and mental energy).）
• Meaning: To expend an enormous amount of mental effort, care, and thought to achieve a specific goal. It emphasizes the 'labor of the mind'—thinking deeply, worrying, and devising intricate ways to solve a problem or create something.

2. Detailed Meaning and Nuances

「煞费苦心」 contains the following nuances:

• Mental vs. Physical Labor: Unlike idioms that describe physical toil, 煞费苦心 (shà fèi kǔ xīn) specifically emphasizes mental strain, worrying, and the 'bitterness' of deep thinking.
• Neutral Nuance: The idiom itself is neutral. Its 'temperature' changes based on the goal: it is a compliment when applied to education or research, but a criticism when applied to plotting or deception.
• The Role of 'Sha' (煞): In this context, 煞 (shà) functions as a colloquial adverb meaning 'extremely.' It signals that the effort is not just ordinary, but extraordinary.

• The character 煞 (shà) originally refers to an 'evil spirit' or 'to kill,' but in modern vernacular Chinese, it is frequently used as an intensifier for adjectives or verbs, similar to how 'deadly' or 'wicked' might be used in English slang to mean 'very.'
