What it means
だった is the familiar past form of the copula. It means “was” or “were” and is used to describe a past identity, category, or state. It follows a noun or a na-adjective directly. The polite equivalent is でした.
Usage note
だった is familiar and should be replaced with でした in polite situations. Do not attach it directly to an i-adjective or verb; those word classes use their own past forms.
