ステキ だ ね — Tae Kim's Japanese Grammar flashcard

[This is] wonderful, isn't it?

ne: sentence ending particle that someone is looking for agreement.

"suteki da" declares that something is wonderful. Sounds familiar? Yes, we learned that "da" is attached to a noun and declares the state of being. But wasn't "suteki" also a na-adjective? Yes, na-adjectives and nouns are pretty much the same! If you look up a word e.g. on jisho.org, you'll often see "noun, na-adjective" as word type.

Don't worry about the difference. Just keep in mind that:

• noun + da declares the noun as state-of-being.
• noun + na acts as adjective, describing another noun.
• noun and na-adjectives are pretty much the same.
