鱼雷
How to Understand
鱼雷 (yú léi) is a noun meaning 'torpedo' in English. It refers to a self-propelled underwater weapon used primarily in naval warfare.
The character 鱼 (yú) means 'fish,' and 雷 (léi) means 'thunder.' While the literal translation might suggest something like 'fish thunder,' the term evolved to describe an explosive device that mimics the movement of a fish and operates underwater, similar to how thunder moves quickly and powerfully.
鱼雷 is commonly used in military contexts, especially in discussions about naval technology and historical battles. It is also sometimes used metaphorically to describe something that surprises or shocks unexpectedly, though this usage is less common. In modern Chinese, it is often taught in military or technical vocabulary.
