出处：“not until” 的起源与英语语法结构的发展演变相关。“not” 作为否定词，“until” 表示“直到……为止”，二者结合形成 “not until” 结构，在英语书面和口语表达中逐渐固定下来并广泛使用。

意思：直到……才，表示某一动作或状态一直持续到某个时间点才发生改变 。

用法：

用于简单句：主语 + 谓语（否定形式）+ until + 时间/事件。例如：He didn't leave until midnight.（他直到午夜才离开。）

用于强调句：It is/was not until + 时间/事件 + that + 句子其他部分。这种结构用于强调时间或事件，例如：It was not until he came back that I went to bed.（直到他回来我才上床睡觉。）

用于倒装句：Not until + 时间/事件 + 助动词 + 主语 + 谓语 + 其他成分。当 “not until” 位于句首时，句子要部分倒装，例如：Not until the rain stopped did they start the game.（直到雨停了他们才开始比赛。）

词语搭配：

与表示时间的名词搭配：not until morning（直到早上）；not until next week（直到下周）

与表示事件的名词搭配：not until the exam（直到考试）；not until the meeting（直到会议）
