TRACK 3 · 3-3
Adjective Present: Positive & Negative
Make polite present/non-past positive and negative statements with both adjective classes.
- Know い vs な adjective classes.
You can now evaluate systems and situations positively or negatively: fast/not fast, convenient/not convenient, difficult/not difficult.
1. The negative transformation differs by class
い-adjective: keep the stem and change final い → くないです. な-adjective: adjective + ではありません (or common じゃありません).
2. Evaluate a system deliberately
Keep the noun constant and change only the description.
Natural: This server is fast.
Structure: this server topic — fast — polite
い positive.
Natural: This server is not fast.
Structure: this server topic — fast-not — polite
い negative.
Natural: This tool is convenient.
Structure: this tool topic — convenient — polite
な positive.
Natural: This tool is not convenient.
Structure: this tool topic — convenient — is-not
な negative.
3. Separate grammar from opinion
A correct sentence can express a questionable opinion. Grammar validates structure, not whether the system truly is fast or safe—an important developer-style distinction.
4. Technical evaluation sheet
Choose six systems/tools/tasks. For each, write one positive and one negative adjective statement. Use both adjective classes.

Use controlled adjective refactors.
Language IDE
Why here: Positive/negative changes differ by adjective class and are ideal for side-by-side inspection.
How to use it for this lesson: Refactor 速いです→速くないです and 便利です→便利ではありません. Explain why the algorithms differ.
Refactor adjective polarity →Mastery checkpoint
Answer without looking back. Use any miss to identify the exact rule or vocabulary gap that needs another pass.
