な-adjectives + です

Xは〜です / 〜な + Noun

Meaning

Describes X using a な-adjective, in the polite present tense.

Explanation

な-adjectives (like 静か or 便利) behave more like nouns grammatically: です attaches directly and does act as a genuine copula here. The な only appears when the adjective directly modifies a following noun (静かな部屋, "a quiet room") - drop it when the adjective ends the sentence before です.

Formation

Noun + は + な-adjective + です / な-adjective + な + Noun

Examples

この公園は静かです。
このこうえんはしずかです。
This park is quiet.
便利なアプリですね。
べんりなアプリですね。
That's a convenient app, isn't it.
