Questions & Answers about namagomi no ryou ni oujite, youki o erabimasu.

How are the main words in this sentence read?

Here are the most important readings:

• 生ごみ → なまごみ
• 量 → りょう
• 応じて → おうじて
• 容器 → ようき
• 選びます → えらびます

A common point of confusion is 生, because it has many readings in Japanese. In 生ごみ, it is read なま.

What does 生ごみの量 mean literally?

生ごみの量 literally means the amount of food waste.

Breakdown:

• 生ごみ = food waste / kitchen scraps
• の = links nouns, similar to of
• 量 = amount, quantity

So A の B means something like B of A or A’s B.
Here, 生ごみの量 = the quantity of food waste.

Why is 量 used instead of 数 here?

量 is used for amount/volume, while 数 is used for number/count.

Garbage is usually thought of as something measured by amount, not by how many individual pieces it contains. So:

• 量 = amount of garbage
• 数 = number of items

That makes 生ごみの量 sound natural, while 生ごみの数 would usually sound odd unless you were counting separate pieces for some special reason.
