〜ものだ (~mono da) — that's how it is / one should
"That's just how people are" — the way of the world and general norms.
Formula (सूत्र ढाँचा)
Grammar rule (व्याकरण नियम र परिभाषा)
Meaning
- Unlike Lesson 10's 「〜たものだ」(used to), 「〜ものだ」without た says two things.
- First, "that's the way it is, it's natural": 「人はみんな失敗するものだ」= everyone makes mistakes, that's how it is.
- Second, a general norm or piece of advice, "one should": 「約束は守るものだ」= promises are meant to be kept.
How to attach
- The negative 「〜ものではない」= one shouldn't: 「人の悪口を言うものではない」.
- In speech, 「〜もんだ」.
Versus what you know
N3Softer than べきだ, with the sense "that's what everyone does".
