该书

该书 is a pronoun meaning 'that book' in Chinese. It refers to a specific book previously mentioned or known in context, similar to 'that book' in English. Unlike general terms like 'book,' 该书 emphasizes specificity and reference to a particular work.

The character 该 (gāi) means 'that' or 'this,' often used to indicate something previously mentioned. The character 书 (shū) means 'book.' Together, they form a phrase that identifies a specific book in conversation or writing.

该书 is commonly used in academic, literary, or formal contexts to refer to a particular text. It helps avoid ambiguity by specifying which book is being discussed. In daily speech, it can appear in discussions about reading materials, research, or references.
