ototoxic

the term "ototoxic" is a modern scientific compound, directly constructed from classical roots to describe a specific pharmacological effect. the first element, "oto-", is derived from the ancient greek word for ear, preserving its anatomical reference. the second element, "toxic", originates from the greek concept of arrow poison, which evolved in latin to signify any poisonous substance. when combined, these morphemes create a precise, literal meaning—"poisonous to the ear"—which accurately defines the word's modern medical usage concerning substances that can impair hearing or balance.

Structure: oto (ear) + toxic (poisonous) - oto: from greek ous (genitive ōtos), meaning "ear". - toxic: from latin toxicum, meaning "poison", itself from greek toxikon pharmakon, "poison for arrows", from toxon, "bow, arrow".
