When to use it

This entry covers ものだ for general truths and common sense: what people naturally do or should do. It is used to give advice or remind someone of social rules, as in 人ひとに何なにかをしてもらったら、お礼れいを言いうものだ (when someone does something for you, you should thank them).

Nuance

Neutral to slightly formal. It sounds like a reminder from someone older or wiser, so it can feel preachy when said to a superior. It describes what is natural or proper in general, not a personal order to one person.

Compare

べきだ states the speaker's own opinion of what is right: もっと勉強べんきょうするべきだ. ものだ presents it as common sense: 若わかいうちは苦労くろうするものだ. ものではない is the negative: 人ひとの悪口わるぐちを言いうものではない. ものだ can also express nostalgia (よく遊あそんだものだ), a different use.

Tip: Add "that is just how it is" in your head. If it fits, the general-truth ものだ is right.
