底部

底部 means 'bottom' in English, referring to the lowest part of something. It can be physical, like the bottom of a container, or metaphorical, such as the base of a structure or the foundation of an idea.

The character 底 (dǐ) originally meant 'base' or 'foundation,' and 部 (bù) refers to 'part' or 'section.' Together, they form a compound that specifically denotes the lower or foundational part of something.

底部 is commonly used in both everyday language and technical contexts. For example, it appears in phrases like 瓶子的底部 (the bottom of a bottle) or 思想的底部 (the foundation of an idea). Understanding this term helps learners grasp spatial and conceptual relationships in Chinese.
