The Vietnamese word "cặm cụi" is both a verb and an adjective that describes someone who is completely focused or absorbed in their work, often to the point of being unaware of their surroundings. It conveys a sense of diligence and dedication to a task.
Cặm cụi cả ngày trong phòng thí nghiệm.
(To be completely wrapped up in one's work in the laboratory all day.)
Cặm cụi tháo lắp cái máy.
(To be completely wrapped up in dismantling and reassembling a machine.)
In more advanced contexts, "cặm cụi" can be used to describe a person’s character or work ethic. For instance: - Anh ấy cặm cụi làm việc, không để ý đến xung quanh.
(He is so engrossed in his work that he doesn't notice what's happening around him.)
The word primarily conveys a sense of being absorbed in work or study, and it does not have significantly different meanings in other contexts. However, it can imply a level of intensity and seriousness in one’s engagement with a task.
