The word "明媚" is formed by combining the character 明, meaning bright, which is composed of the radicals 日 (sun) and 月 (moon) to denote light, with the character 媚, meaning charming, which consists of the radical 女 (woman) and the phonetic component 眉 (eyebrow) to suggest attractiveness; together, they create a compound where the meanings merge to describe something bright and beautiful, such as sunlight or scenery.
