柱子

"柱子" (zhù zi) means "column" in English. It refers to a vertical support structure, often used in buildings or architecture. It is more specific than the general term "post" and usually implies a stronger, more permanent structure.

The character "柱" (zhù) originally meant a pillar or post, derived from its shape and function. "子" (zǐ) is a common suffix used to denote something small or a child, but in this case, it functions as a noun-forming suffix, turning "柱" into a concrete object.

In daily life, "柱子" is commonly used in construction, interior design, and even metaphorically, such as "中流砥柱" (zhōng liú dǐ zhù), meaning "the backbone of a cause." It is also used in idioms and proverbs to symbolize strength and stability.
