The Vietnamese word "lọn" is a noun that generally means a "curl," "ringlet," or "lock" of hair. It refers to a small section or strand of hair that has been curled or twisted in a spiral shape.
In more advanced contexts, "lọn" can be used metaphorically to describe something that is spiraled or twisted, not just limited to hair. However, this usage is less common and primarily used in poetry or artistic descriptions.
