根据

根据 means 'based on' or 'according to' in English. It is used to indicate the foundation or source of a statement, decision, or conclusion.

The character 根 (gēn) originally meant 'root' and symbolizes the foundation or origin. 据 (jù) means 'evidence' or 'basis.' Together, they form a phrase that indicates something is derived from a specific source or reference.

根据 is commonly used in formal and academic contexts, such as in writing reports, making arguments, or citing sources. It is also used in everyday conversations when explaining the basis for an opinion or action. For example, “根据天气预报，我们决定去野餐。” (Based on the weather forecast, we decided to go on a picnic.)
