Nはな-adj{な}です Nはい-adj(〜い)です
Pattern
Explanation
Adjectives
Adjective sentences that are non-past and affirmative end in です, which shows politeness toward the listener. Both types of adjective are attached to the front of です, but な-adjectives drop their な, while い-adjectives retain their (〜い).
Negative Forms
The non-past negative of a な-adj is formed by dropping the な and attaching じゃ(では)ありません to it. The non-past negative of an い-adjective is formed by dropping the final い and attaching くないです to it.
[Note] The negative of いいです is よくないです.
Adjectival Inflections
- Non-past affirmative: しんせつです
- Non-past negative: しんせつじゃ(では)ありません
- Non-past affirmative: たかいです
- Non-past negative: たかくないです.
Questions
Questions using adjective sentences are formed in the same way as those using noun sentences and verb sentences. To answer such a question, the adjective is repeated.
Expressions such as そうです or ちがいます cannot be used.
