The Vietnamese word "rốn" is a noun that means "navel" or "belly button" in English. The navel is the small, central scar on your abdomen where the umbilical cord was attached when you were a baby. It is a common term you will hear in everyday conversation and can be used in various contexts.
In more advanced contexts, "rốn" can be used in idiomatic expressions or figurative language. For instance, it can describe something as being central or crucial, much like how the navel is the center of the body.
While "rốn" primarily refers to the navel, it can also have a figurative meaning related to being the center of something, similar to the way we use the term "hub" in English.
In Vietnamese culture, the navel may not have significant cultural connotations, but it is often mentioned in health-related discussions, such as in traditional medicine or when talking about body care.
