Reaching a result with 到

Core idea

到 can follow a verb to show that the action reached its target or succeeded.

This use appears with verbs such as find, buy, hear, see, receive, or wait for.

Result, not just direction

You already know 到 for arriving somewhere. As a result complement, it does the same kind of work in a more abstract way: the action reaches what it was aiming for.

Usage boundary

Use this pattern when the success of the action matters. If you only want to say someone tried looking, buying, or listening, the bare verb may be enough.
