Whats in a language? - Ano ang tagalog? I

What is in a language? So interesting after 5 years through studying intensive tagalog (filipino) I learn, more and more, deeper and deeper. My guro’s/maestro’s/titsers say (a lot) they explained me pasok, to enter, pumasok ka, you enter. Pasok by itself is not good, because who is entering? Who else is behind the fence hiding, waiting to be fed as well? So in dutch we would ask, where to enter, front door, backdoor, kitchen door? In tagalog it is understood, where you enter. Wondering where it is coming from….?
