私 sī

Core Meanings: Private; personal; one’s own (opposite of 【公】, gōng, public); selfish; secretly.

To remember the Chinese character 【私】, start with its right half: the two-stroke character 【厶】. Imagine drawing a tight, closed loop around something—this self-enclosing shape perfectly captures the idea of “what’s mine.”

In agrarian China, nothing symbolized personal property more than grain. So our ancestors combined 【厶】 with 【禾】 (grain/crop) to create 【私】, emphasizing “my grain, my private possession.” Ancient Chinese dictionaries also confirm this connection, defining 【私】 as closely related to personal belongings and private wealth.

💡 Memory Hack

Link the structure to a clear story: 【禾】 + 【厶】 = 【私】. Think: “I circle (【厶】) my grain (【禾】)—it’s all private (【私】)!” This logic also reveals its opposite: 【公】 (public) literally means “turning one’s back on 【厶】.”

Common words like 【私人】 (private person), 【私信】 (private message), and 【私有】 (privately owned) all grow from this ancient root—proving how 【私】 still shapes how we talk about “mine” today.
