Questions & Answers about baiyoudo ni fuyoudo o mazeru.

How do you read the words in this sentence?

• 培養土 = ばいようど
• に = に
• 腐葉土 = ふようど
• を = を (pronounced お in modern Japanese)
• 混ぜる = まぜる

So the whole sentence is read:

ばいようど に ふようど を まぜる。

What does the particle に mean here?

Here, に marks the thing that something is being added to.

So in:

培養土に腐葉土を混ぜる

the 腐葉土 is being mixed into the 培養土.

A useful way to think about it is:

• A に B を 混ぜる = mix B into A

So に does not mean a general location here. It shows the target/base material.

Why is 腐葉土 marked with を?
