About ものと思う

(もの)(おも) is made up of the noun (もの) 'thing', the case marking particle と, and the う-Verb (おも)う 'to think'. Regular translations include 'to believe that (A)', or 'to have confidence that (A)'. In a broader sense, this grammar pattern is just making use of one of the meanings of (もの) as being something abstract that the speaker can reliably determine has all of the qualities of something concrete.
As もの is a noun, this pattern may follow any word in its attributive form.
  • あの(ひと)はなんでもできると自信(じしん)ありげに()っていたんで、仕事(しごと)ができるものと(おも)っていたが全然(ぜんぜん)だった。
    He said confidently that he could do anything, so I expected him to be capable of doing the job, but he was not at all.
  • (おっと)部屋(へや)からものすごいキーボードの(おと)()こえたから、(いそが)しいものと(おも)っていたがただゲームをしていただけだ。
    I heard my husband typing on his keyboard, so I was confident that he was busy, but he was just gaming.
  • 結婚(けっこん)(しあわ)せなものと(おも)(ひと)(おお)いだろう。
    Many people believe that marriage is a happy thing.
  • 日本(にほん)(もっと)(さむ)(つき)は12(がつ)であるものと(おも)っている(ひと)(おお)いが、(じつ)は2(がつ)だ。
    Many people think that the coldest month in Japan is December, but actually it is February.
When (おも)う appears in the past tense, the most common translation is 'as I had believed was true of (A)', or 'I was under the impression that (A)'.
  • 外国人(がいこくじん)観光客(かんこうきゃく)日本語(にほんご)(はな)せないものと(おも)っていたが、実際(じっさい)そうでもなかった。
    I was under the impression that foreign tourists could not speak Japanese, but this was not the case.
Although this grammar construction is slightly formal, it may occasionally be heard in daily speech.
