Question: what is the difference between ng and nang?
Answer: We use 'ng' when you want to say of, like Perlas ng Silangan, which translates to Pearl of the Orient/East. We use 'nang' when you want to say so that, like magpayong ka nang hindi ka mainitan, which translates to, use an umbrella so that you'll not feel hot. “Ng” is actually suffix while “Nang” is a preposition.
