The Chinese word "坚强" is formed by combining two individual characters, each contributing its core meaning to create a compound concept. The first character, "坚", conveys firmness, solidity, or unyielding hardness, often in a physical or metaphorical sense. The second character, "强", adds the dimension of strength, power, or vigor. When merged, these characters reinforce each other to express a holistic idea of resilience and steadfastness, specifically describing a person's inner fortitude or the quality of being tough and persistent in the face of adversity. This formation relies on semantic alignment, where both elements emphasize aspects of durability and power, resulting in a word that encapsulates emotional and moral strength.
