白 + Verb + 了 (wasted effort)

• 拼音: bái
• 结构: 白 + Verb + 了
• 汉字拆解: 白 = pictograph representing whiteness or blankness; figuratively extended to mean 'in vain' from the sense of emptiness

含义

Indicates that an action was performed in vain or that the effort was completely wasted. The adverb 白 is placed before the verb, and 了 follows the verb to mark that the action has been completed to no useful effect. This pattern often carries frustration or regret.

The figurative use of 白 meaning 'in vain' or 'for nothing' derives from its original meaning of 'white' or 'blank,' evoking emptiness and lack of result. In the pattern 白 + V + 了, the completed action yields no benefit whatsoever. This pattern is extremely common in spoken Chinese and is used to express everything from mild disappointment to strong frustration. Beyond the past tense 白 V 了, the pattern also works as a prospective warning: 去了也是白去 means 'even if you go, it would be a waste.' Related expressions include 白白浪费 (completely wasted), 白费力气 (wasted effort), and 白忙一场 (busy for nothing). The key structural point is that 白 must directly precede the verb, functioning as an adverbial modifier.

例句

1. 说了半天，他根本没听进去，我算是白说了。
2. 你不提前预约的话，去了也是白去。
3. 排了两个小时的队，最后票卖完了，白排了。

• 准备了一桌子菜，客人临时取消了，全白做了。
• 那个项目最终被取消了，我们白忙了三个月。

错误说法

• 我白跑趟了。(白 must directly precede the verb and 了 must follow the verb — for phrases with measure words, structure as 白跑了一趟) → 我白跑了一趟。
• 这些钱白了花。(了 must follow the entire 白 + Verb construction — the structure is 白花了, not 白了花) → 这些钱白花了。

起源与历史

The character 白 originally meant 'white' and was a pictograph of the sun with a ray of light. Its figurative extension to mean 'in vain' comes from the concept of blankness and emptiness — an action done for nothing yields a blank result.
