Meaning and Usage
"坚硬" describes something that is physically hard, solid, or firm. It often refers to materials like stone, metal, or other substances that resist pressure or deformation. Beyond physical hardness, it can metaphorically describe a person's will or attitude as firm and unyielding.
Common Collocations
- 坚硬的石头 (hard rock): emphasizes physical toughness.
- 意志坚硬 (firm will): used metaphorically for mental strength.
- 坚硬耐用 (hard and durable): often used in product descriptions.
Usage Notes
"坚硬" is more formal and descriptive than just "硬" alone, which can be more general. When describing people’s character, "坚硬" implies strong determination rather than stubbornness. Avoid confusing it with "坚强," which focuses more on emotional resilience.
Summary
Use "坚硬" when emphasizing the solid, tough nature of objects or the firmness of abstract qualities like willpower. It fits well in both literal and figurative contexts, especially in written or formal speech.
