Some people use “trust” as a two-placed verb: “I trust Amy”. The two “places” are for the subject (me) and the object (Amy).
I think that this way of using the word “trust” often collapses things down too much. People have very different skills and attributes, and it’s often worth differentiating what you trust them on.
Instead, you should say things like “I trust Amy to summarize the implications of lawyers’ advice” or “I trust Bill to keep confidences”. These have three places: subject, object, and a modifier specifying the domain in which you trust the person.1
I guess people most often use “trust” to mean things like “trust not to be a dick”, “trust to cooperate with us when the going gets rough” or “trust to have good judgement in most cases” — but these are all pretty different!
