可以想成一種一旦進到活體裡就會悄悄傷害、甚至致命的東西——就像塗在箭頭上的毒。toxic 講的就是帶著這種「會害人」力量的性質。From the word’s history
From Greek toxikon (pharmakon) '(poison) for use on arrows', from toxon 'bow'. Ancient hunters coated arrowheads with poison, so the word for archery came to mean the poison itself — that arrow-poison is the seed of every modern 'toxic'.
源自希臘文 toxikon (pharmakon)「用在箭上的毒」，再往上是 toxon「弓」。古代獵人在箭頭抹毒，於是「跟弓箭有關」的字反過來指那個毒藥本身——這支「毒箭」就是今天所有 toxic 的種子。
