自

• 拼音: zì
• 汉字拆解: 自 = pictograph of a nose, symbolising 'oneself' or the self as origin

含义

From; since; self. Used as a preposition meaning 'from' a place or time, or as a prefix meaning 'self-'.

As a preposition, 自 is more formal than 从 and often appears in written Chinese to indicate a starting point in time or place (e.g., 自古以来 'since ancient times'). As a prefix in compound words, it expresses the idea of doing something by oneself or independently (e.g., 自学, 自由, 自然).

例句
