The word 明确 is formed by combining two individual characters, each contributing a core concept to create a new, unified meaning. The first character, 明 (míng), originally depicts the sun (日) and moon (月) together, conveying "bright" or "clear". The second, 确 (què), carries the idea of something solid, real, or verified. When joined, they create a conceptual blend where the clarity and illumination of 明 is fused with the firmness and reliability of 确, resulting in the comprehensive sense of something being "clear and definite" or "to make clear".
