及其
How to Understand
其 is a pronoun meaning 'its' or 'their,' and 及 means 'and' or 'as well as.' Together, 及其 functions as a conjunction to mean 'and its' or 'as well as its,' often used to connect a subject with its associated items or attributes.
The character 及 (jí) originally meant 'to reach' or 'to arrive at,' and over time it evolved into a conjunction meaning 'and' or 'as well as.' 其 (qí) is a pronoun that typically refers to 'its' or 'their,' depending on context. When combined, they form a phrase that links a subject with its related elements.
及其 is commonly used in written Chinese to show a relationship between a main subject and its components or effects. It is often found in formal or academic writing, such as in descriptions of systems, processes, or hierarchical structures. Understanding its usage helps learners grasp more complex sentence patterns in Chinese.
