Questions & Answers about aoi yuuyaku o erabu.

How do you read 釉薬?

It is read ゆうやく.

• 釉 = ゆう
• 薬 = やく

釉薬 means glaze in the pottery / ceramics sense, so this is a somewhat specialized word rather than everyday basic vocabulary.

Why is it 青い 釉薬 and not 青な 釉薬?

Because 青い is an い-adjective.

In Japanese, い-adjectives modify nouns directly:

• 青い釉薬 = blue glaze
• 大きい皿 = a big plate

Only な-adjectives use な before a noun:

• 静かな部屋 = a quiet room

So 青な釉薬 is incorrect.

What is the role of を here?
