嵌入结构(Embedding structure)是指将一个语言或文本中的某些结构嵌入到另一个结构中的过程。这种结构是在语言发展过程中形成的,是为了表达更复杂的意思或更精确地表达某种关系而出现的。

例如,在英语中,我们可以将一个定语从句嵌入到另一个定语从句中来表达更复杂的意思:

The man who I saw yesterday, whose car was parked in front of the store, told me that he was in a hurry.

在这个例子中,"whose car was parked in front of the store"是一个嵌入在"The man who I saw yesterday"中的定语从句。

另一个例子是将一个状语从句嵌入到另一个状语从句中:

I'll call you as soon as I finish the report, provided that I have your phone number.

在这个例子中,"provided that I have your phone number"是一个嵌入在"as soon as I finish the report"中的状语从句。

嵌入结构是英语中常见的一种语法结构,可以帮助我们表达更复杂的意思或更精确地表达某种关系。
