키우다 is raising a child, an animal or anything you grow, and what comes before with -아/어 says how. Two set phrases appear: 먹여 키우다, feeding something up (돼지를 먹여 키운대요), and 업어 키우다, raising a child carried on your back — which stands for having brought someone up from infancy and is used jokingly between colleagues, as in 형이 업어 키웠는데.
