The Vietnamese word "nhăn" is an adjective that describes something that is crumpled, wrinkled, creased, or furrowed. It is often used to describe physical appearances, particularly on skin or fabric.
In a more advanced context, "nhăn" can describe not just physical wrinkles but also metaphorical ones. For example, you might use it to describe a situation that has become complicated or difficult, similar to how wrinkles make fabric look less smooth.
While "nhăn" primarily refers to wrinkles or creases, it can also be used in a more figurative sense to describe a person’s demeanor. For example, someone with a "nhăn" expression might look worried or troubled.
