JLPT N1Careful, officialSettled expectation

ものと思おもう・ものと思おもっていたI trust that; I had assumed

もの makes a belief the natural reading of things, not a passing opinion: "I trust that", "I expect that". Careful and official. ものと思おもっていた is "I had taken it for granted that", usually just found wrong, and that one is everyday.

What もの adds: Firmer than と思おもう, and less personal: this is how things are bound to turn out.
You'll hear: ご理り解かいいただけるものと思おもいます, "I trust you will understand".
