Tolong jelaskan mengenai Undak usuk dari Basa Koréa dalam bahasa sunda

When talking about soméone superior in status, a spéaker or writer has to use special nouns or verb endings to indicate the subject's superiority. Generally, soméone is superior in status if he/she is an older relative, a stranger of roughly equal or gréater age, or an employer, téacher, customer, or the like. Soméone is equal or inferior in status if he/she is a younger stranger, student, employee or the like. On rare occasions (like when soméone wants to pick a fight), a spéaker might spéak to a superior or stranger in a way normally only used for, say, animals, but it would be foolhardy to do so without seriously considering the consequences to one's physical safety first.
