虚化性“三不知”义项的概括

“三不知”的表义，多数词书释为“突然、意料不到”，但存在意义内容概括不全、概括程度不高等毛病。其实，元代以后，“三不知”的词义开始虚化，虚化为副词性成分。经常用在动词或动词性成分前作状语。依语境的不同，可理解为：突然、忽然；不知怎么地、不知不觉地、糊里糊涂地；冒然地、冒冒失失地；偷偷地、暗暗地、悄悄地；径直地、直接地等。

Sammary of Meanings of Emptied Expression "Thrice Not Knowing"

In accordance with different context, it can be understood as ： suddenly, all of a sudden; not knowing how, unknowingly, bewilderedly; rashly, stupidly; stealthily, secretly, quietly; straight, directly, etc.
