ではなかった・ じゃなかったWas not; were not6 common forms
These endings say that someone or something was not a particular person, thing, category, role, or state at a past time. Attach one complete ending directly to a noun.
Meaning and use
Use these forms when the final description is a noun and that description was not true at an earlier time. A past-time word or the surrounding conversation usually makes the time reference clear.
Core examples
Notice that each sentence ends with a noun followed by one complete past-negative ending.
Use it after nouns
These endings negate a noun-based description, such as a job, identity, place in a schedule, or kind of object. To say that an action did not happen, use the past-negative form of the verb instead.
