foster, bring up, rear, develop, nurture
養 centers on providing sustained care so that something grows or thrives: fostering children, rearing animals, developing skills, or nurturing well-being.
養 combines 食 (food/eat) with a phonetic component derived from 羊 (sheep), suggesting the idea of providing food to raise or nurture. The upper part historically relates to 羊, and the whole character expresses fostering through sustenance.
The bottom is 食 (food/eat), and the top looks like a sheep 羊 with extra strokes. Picture feeding a sheep to raise it: providing food is how you foster and nurture growth.
For ヨウ, imagine a young sheep being fostered: young -> ヨウ, and you are bringing it up with care.
