凡是 (as long as / all that)

• 拼音: fánshì
• 结构: 凡是 + Noun (+ Modifier) + 都 / 就 / 一律 + Predicate
• 汉字拆解: 凡 = 几 (table) + 丶 (dot), meaning ordinary/all; 是 = 日 (sun) + 疋 (correct), meaning to be

含义

凡是 (fánshì) means 'all that,' 'every,' or 'as long as it is.' It introduces a universal category or condition, asserting that everything meeting the stated criterion shares the same outcome or characteristic.

凡是 creates a sweeping, categorical statement — it says 'without exception, everything that fits this description...' The result clause typically contains 都 (all), 就 (then), or 一律 (uniformly) to reinforce the universal scope. Unlike 只要 which sets a conditional ('if only...then'), 凡是 categorizes and includes all members of a group. It carries an authoritative or emphatic tone, common in regulations, proclamations, and strong assertions. The noun following 凡是 is usually modified by a relative clause or descriptor that defines the category.

例句

正确说法

• 凡是符合条件的申请者都可以参加面试。
• 凡是迟到的学生就不能进入考场。
• 凡是她做的菜，大家都抢着吃。

错误说法

• 凡是他昨天来了。(凡是 introduces a category, not a specific event — it cannot describe a single past action) → 他昨天来了。
• 凡是下雨，我带伞。(凡是 requires 都/就/一律 in the result clause to complete the categorical statement) → 凡是下雨天，我都带伞。

起源与历史

凡是 combines 凡 (ordinary/all) and 是 (to be). In Classical Chinese, 凡 alone meant 'in all cases' or 'generally.' Adding 是 reinforced the categorical assertion, creating a stronger universal quantifier.
