Learn Hardcore Filipino: Nasa sine kami.

Filipino often does not use a separate present-tense verb like English am / is / are in simple location sentences. The sentence is still complete without it.

So Nasa sine kami naturally means we are at the cinema / movies even though there is no separate word for are.

What does nasa mean here?

Nasa shows location. In sentences like this, it works like is/are at, is/are in, or is/are on, depending on the place.

So:

Nasa bahay ako = I am at home
Nasa opisina siya = He/She is at the office
Nasa sine kami = We are at the cinema

A learner can treat nasa as the normal form used to say where someone or something is.

What is the difference between nasa and sa?
