This Greek element originally meant "bow", then it became "arrow", then a "poisoned arrow" and finally "poison". In most cases, toxico- means poison, but in a few situations it refers to the original meaning of "arrow", as in toxophilite and toxophily; "love of or fondness for archery", and so it shouldn't be confused with toxophil, toxophile, "having an affinity for or an attraction to a toxin or poison'.
