Etymology
the word 'insecticide' is a modern scientific compound, formed by combining two classical elements. the first part, 'insect', originates from the latin 'insectum', which itself is a translation of the greek 'entomon', both meaning 'cut into' and describing the creature's segmented body. the second part, '-cide', derives from the latin verb 'caedere', meaning 'to cut down' or 'to kill'. the connecting 'i' is a typical latin linking vowel. therefore, the term literally and logically means 'insect-killer', a meaning that has remained transparent from its 19th-century coinage to its modern usage.
Analysis
insect (from latin 'insectum', meaning 'cut into, segmented', referring to the segmented body of the creature; functions as the base noun). i (a connecting vowel, often from latin or greek, used to join word elements). cide (from latin '-cidium', a derivative of 'caedere', meaning 'to cut, to kill'; functions as a suffix denoting an agent or substance that kills).
