How to form it
といい attaches to nouns. To use an adjective or verb idea, change it into a noun first.
| Word type | How it attaches | Example |
|---|---|---|
| Noun | Noun + といい | 色といい形といい |
| い-adjective | Change to a noun with さ | 高さといい重さといい |
| な-adjective | Change to a noun with さ | 便利さといい安さといい |
| Verb | Use a related noun | 歌う → 歌といい |
| Register | Ending |
|---|---|
| Polite | ～です。 |
| Casual | ～だ。／～だね。／～だよ。 |
The pattern sounds a little formal, but it is used in both speech and writing.
