5. History

Liushu category: Phono-semantic (形声)

Origin: Originally combined '采' (to pluck or gather) with '心' (heart/mind), depicting the mental act of gathering information or details into one's consciousness to fully grasp them.

Semantic Evolution: Shifted from the physical act of gathering into the mental state of knowing completely and thoroughly, and further extended to mean 'all' or 'in all cases' in literary texts.

Often found in formal correspondence and official documents in compounds like 获悉 (to learn of).

8. Mastery

Active Recall Challenge

我刚[___]这个消息，我们马上出发吧！

Clue: huò xī

Common Learner Pitfall

Confusing the top component '采' with '受' or writing the bottom '心' as a separate standalone structure instead of tucking it neatly underneath.

Memory Prompts

Recognition: When you see the character 悉, what formal verb meaning 'to know' or 'to be aware of' comes to mind?

Production: How do you write the character for 'to know / thoroughly' (xī), which combines 'gather' (采) on top and 'heart' (心) on the bottom?
