Lesson 187: The Plain Form V: Past Tense Adjectival Sentences

Making a past tense adjectival sentence in the plain form varies by whether the adjective is an い-adjective or a な-adjective.

For い-adjectives the final です is simply dropped after the -かった ending.

English Japanese
The meal was unpalatable. しょくはまずかった。
shokuji wa mazukatta.
Your answer was not correct. あなたのこたえはただしくなかった。
anata no kotae wa tadashiku nakatta.

For な-adjectives, the adjective is followed by the plain past form of the copula, だった. And for the negative form, we drop the polite です after じゃ なかった.

English Japanese
Mary liked it very much. メアリーさんはとてもきだった。
mearii san wa totemo suki datta.
The library was not quiet. しょかんしずかじゃなかった。
toshokan wa shizuka ja nakatta.
