Noun
そとぼり
ちょっと気が変わって、外堀は必要がないようと思うようになりました。
I’ve changed my mind, I don’t think we need an outer moat.
The outside ditch is the ditch around our town that's on the outside (not the inside ditch, which is the inner moat). This is the outer moat.
This word uses the same readings from the previous vocabulary except that 堀 gets rendakued - don't forget!
