Grammar Rule in 30 Seconds
Na-adjectives describe nouns and require the particle 'na' when placed directly before a noun.
- Use 'na' before a noun: {静か|しずか}な{部屋|へや} (a quiet room).
- Drop 'na' and use 'desu' at the end: {部屋|へや}は{静か|しずか}です (The room is quiet).
- Use 'ja arimasen' for negative: {静か|しずか}ではありません (It is not quiet).
