。
She didn't go there.
Literal
She [topic-は] there [to-へ] did-not-go.
A clean four-word sentence demonstrating bare negative past in Japanese. 行く ('go') becomes 行かなかった: drop the ku, add か (the negative-stem signal for 五段 verbs), then なかった (the past form of the negative auxiliary). The pattern of building negation in plain past goes ない → なかった across the board. Despite its simplicity, the sentence still reveals the subtle へ vs に dance: そこへ行く ('go toward there') versus そこに行く ('go to there') — both natural, with へ slightly emphasizing the direction.
