Questions & Answers about Saya tersesat di pasar malam.
Di is a preposition meaning “at” or “in” when indicating location. So di pasar malam = “at the night market.”
By contrast, ke is a directional preposition meaning “to.” You would use ke pasar malam in a sentence like Saya pergi ke pasar malam (“I go to the night market”), but not when saying where you’re lost.
