malathion
UK[ˌmæləˈθaɪən]US[ˌmæləˈθaɪɑːn]
n
a synthetic organic compound used as an insecticide, especially against aphids and other plant-sucking insects.
Etymology
the word 'malathion' is a modern scientific coinage, originating as a trademark name for the insecticide. it was created in the 1950s by the american cyanamid company, deriving it from 'malic acid' and 'thion-', a chemical suffix indicating the presence of sulfur. 'Malic acid' itself comes from the latin 'malum', meaning 'apple', as the acid was first isolated from apple juice. thus, the name's literal construction hints at its chemical relationship to malic acid and its sulfur-containing molecular structure, though it functions as an unanalyzable whole in modern english.
Analysis
this is a simplex word. it is a coined trademark name, not formed from productive english morphemes.
