来不及

• 拼音: lái bù jí
• 汉字拆解: 来 = 木 (tree radical, original pictograph); 不 = negation; 及 = 人 (person) + 又 (hand catching up) — unable to catch up in time

含义

To not have enough time; too late to do something. Expresses that there is insufficient time to complete an action.

来不及 is used to indicate that an action cannot be done in time, either because it was started too late or because there is simply not enough time remaining. It is the opposite of 来得及. It is often used with potential complement structure and is a very common expression in everyday speech.

例句

1. 已经八点了，我们来不及赶上那班火车了。
2. 作业太多，昨晚来不及全部做完。
3. 他匆匆忙忙地跑出门，来不及吃早饭。

• 来不及解释了，先跟我走！(There's no time to explain — just come with me!)

错误说法

起源与历史

来 (to come) + 不 (not) + 及 (to reach, to catch up with). Together the phrase means one cannot reach or manage in time — the time is insufficient to 'arrive' at completing the task.
