Study notes
1. Origins, structure, and basic meaning
- Structure: Add
だったafter a noun or a na-adjective stem. - Basic usage: It states a past condition in plain style, as in
この町は静かだった.
2. Common pitfalls and similar expressions
- A past state before a noun
静かな町modifies a town with a quality, while静かだった町identifies a town that was quiet. Do not add the modifyingなagain after the past form.
- Contrast with the present
その日は雨の日だった。characterizes that day as rainy. Stating a past condition does not by itself establish the opposite condition now.
