able to cause death
Able to kill a person or animal, especially a drug, weapon, or illness.
用法模式：
lethal [substance/weapon/dose/blow]
常见错误：
Learners sometimes confuse "lethal" with "fatal". "Lethal" focuses on the ability to cause death (a lethal weapon, a lethal dose), while "fatal" usually describes something that actually leads to death (a fatal accident, a fatal mistake). Also, avoid using "a lethal" as a noun; say "a lethal weapon" rather than "a lethal".

用法模式：
lethal [combination/mix/cocktail/effect]

|

extremely good or impressive
Very informal: extremely good, strong, or effective, especially in sports or competition.
用法模式：
lethal [shot/move/backhand/smile]
常见错误：
Learners may misunderstand this slang use as literally about death. In sports and casual speech, "lethal" often just means very strong or effective, not that anyone is killed. It is not appropriate in formal writing.
近义词
killer (Very informal slang with a similar meaning of "excellent" or "very strong".)
|
deadly (In some dialects, also slang for "excellent"; overlaps with the literal meaning.)
反义词
weak (Describes something that is not strong or effective.)
|
harmless (Suggests it does not have a strong or dangerous effect; opposite of being impressively powerful.)
