The Vietnamese word "bôi trơn" is a verb that means "to lubricate." It refers to the action of applying a substance, typically oil or grease, to reduce friction between surfaces, making movement smoother or easier.
In more technical contexts, "bôi trơn" can be used in discussions about machinery, automotive maintenance, or any situation where reducing friction is important for efficiency and longevity. For instance: - "Việc bôi trơn thường xuyên cho động cơ sẽ giúp tăng tuổi thọ của nó." (Regular lubrication of the engine will help prolong its lifespan.)
While "bôi trơn" primarily means "to lubricate," it can also have metaphorical uses, like "lubricating" a conversation or negotiation, meaning to make it smoother or easier.
