The word 'toxicology' is a modern scientific compound built directly from classical Greek elements. Its first part, 'toxico-', traces back to the Greek toxikon pharmakon, meaning "poison for arrows," derived from toxon (bow). This reflects the ancient association of poison with weaponry. The suffix '-logy', from Greek -logia (from logos, meaning "word, reason, discourse"), signifies a systematic field of study. Thus, the term's literal construction, "the study of poisons," provides a perfectly transparent and logical description of the scientific discipline it names, which investigates the nature, effects, and antidotes of toxic substances.

Structure: toxico (poison) + logy (study of) - toxico: From Greek toxikon (poison for arrows), via Latin toxicum. In this word, it functions as the root, providing the core meaning of "poison." - logy: From Greek -logia, meaning "the study of" or "discourse about." It functions as a suffix denoting a branch of knowledge or science.
