The word "漂亮" is formed through the conceptual combination of its two constituent characters: "漂", which originally conveys a sense of being buoyant, elegant, or washed clean (like floating gracefully on water), and "亮", which means bright, luminous, or clear. Together, they create a composite idea where the elegance and purity suggested by "漂" is intensified and illuminated by the clarity and brilliance of "亮", resulting in the overall meaning of "beautiful" or "pretty", essentially describing something that stands out with a radiant and pleasing elegance.
