☀️ 阳 yang (sun side) + 性 nature = the positive one; in tests it means positive
阳 is the bright yang half of yin-yang, the active or positive pole; 性 means nature or quality. Together: positive (as in a positive test result) or grammatically masculine, the yang-gendered form.
性 — heart radical 忄 + 生 (life/birth)
性 is a semantic-phonetic compound. The heart radical 忄 supplies the meaning, pointing to inner feelings or innate qualities, while 生 ('birth, life') gives the sound and hints at what one is born with. It originally meant 'inborn nature' and later extended to 'character,' 'gender,' and 'sex.'
