Study notes

1. Origins, structure, and basic meaning

  • Structure: Add ではありませんでした after a noun or na-adjective stem.
  • Basic usage: It politely negates a past judgment, as in 昨日は休みではありませんでした。.

2. Common pitfalls and similar expressions

  • Scope of the past negative
    • 昔はレストランではありませんでした says that the place was not a restaurant in the past. Whether it is a restaurant now requires other information.
  • A related polite expression
    • Both 静かではありませんでした and 静かではなかったです politely negate a past state. Do not combine the two ways of forming the past in a single predicate.
