The word 晴朗 is formed by combining two characters: 晴, meaning 'clear' or 'sunny', which is composed of the radical 日 (sun) for meaning and 青 for phonetic indication; and 朗, meaning 'bright' or 'clear', composed of the radical 月 (moon) for meaning and 良 for phonetic indication. Together, they create a compound word where both characters contribute semantically to describe clear, sunny weather.
