数量 + は (suuryou + wa) — At least this much
は after a number sets the floor — at least this much.
Formula (सूत्र ढाँचा)
Grammar rule (व्याकरण नियम र परिभाषा)
When to use it
Use it when you do not know the exact number but you do know it will not be under that.
Meaning
- Putting は after a number or amount makes that number a floor — it will not be less than that.
- 一時間 かかります is just a fact; 一時間は かかります means "it takes at least an hour".
How to attach
- It works with any amount: 三十分は 歩きます, 十万円は いります.
- It is fine even if the sentence already has a は elsewhere (この 仕事は 一時間は かかります).
Versus what you know
- Which to pick? Use は for "not less than this".
- Use も for the surprise of "a full that much!".
