Breakdown of Nasa may-ari ang kontrata.
Questions & Answers about Nasa may-ari ang kontrata.
Nasa usually means is in / is at / is on / is with, depending on context.
In Nasa may-ari ang kontrata, it means something like is with the owner. So the sentence is describing where the contract is, or whose possession/custody it is in.
A useful thing to know is that nasa comes from na + sa in modern usage, but learners usually just treat nasa as a common unit meaning located at/in/with.
Because Filipino often puts the predicate first.
So in:
Nasa may-ari ang kontrata
the part nasa may-ari comes first, and ang kontrata comes after it.
A very natural English-like rearrangement would be:
Ang kontrata ay nasa may-ari.
That has the same basic meaning. Filipino commonly allows both patterns, but predicate-first order is very normal and often sounds more conversational.
