The word 抖擞 is formed by combining two characters, each constructed as a semantic-phonetic compound. The character 抖 uses the hand radical (扌) to indicate action related to shaking, with 斗 providing phonetic approximation, while 擞 similarly uses the hand radical (扌) for meaning and 数 (in its simplified form) for sound, together creating a disyllabic term that conveys the sense of shaking off or invigorating.
