The English translation of paggalang means to be respectful or to give respect to a person.
Filipinos are accustomed to using the words “po,” “opo,” and “ho” when they are conversing with older people or, sometimes, with those who are in a high role or a prestigious member of society. Using these words is customary in the Philippines, and it shows a sign of respect if you do so.
Paggalang can also be shown toward your elders by kissing their hands before leaving/to say goodbye and upon arrival/to greet them.
The younger members of the family can show respect toward older siblings by calling them kuya (older brother) or ate (older sister).
