Questions & Answers about shinjuusho o kakuninsuru.
It’s read:
しんじゅうしょ を かくにんする
Breakdown:
- 新住所 = しんじゅうしょ
- を = pronounced o
- 確認する = かくにんする
So the full reading is:
しんじゅうしょ を かくにんする
The structure is:
- 新住所 = new address
- を = marks the direct object
- 確認する = to confirm / to check
So grammatically, this is:
[object] を [verb]
In other words:
new address + object marker + confirm/check
を marks the thing that the action is done to—the direct object.
Here, the action is 確認する (to confirm/check), and the thing being confirmed is 新住所 (new address).
So:
- 新住所を確認する = to confirm the new address
A native English speaker can think of を as roughly marking what is being acted on.
