The Vietnamese word "cóng" is an adjective that describes a state of being numb due to cold. It is often used to express how someone feels when they are exposed to very low temperatures for a period of time, causing a loss of feeling in their body parts.
In more advanced contexts, "cóng" can be used metaphorically to describe feelings of emotional numbness or a lack of response due to overwhelming situations. However, this usage is less common and typically requires additional context.
While "cóng" primarily refers to being numb from cold, it can also imply a state of inactivity or stiffness, similar to how limbs can feel stiff when they are cold. However, the primary meaning remains related to cold.
