Word origin
[1925–30; poly- + -ene]This word is first recorded in the period 1925–30. Other words that entered Englishat around the same time include: decibel, distinctive feature, hot spot, recycle, turnaroundpoly- is a combining form with the meanings “much, many” and, in chemistry, “polymeric,”used in the formation of compound words. Other words that use the affix poly- include: polyandrous, polyculture, polyethylene; -ene is a suffix used to form names of unsaturated hydrocarbons (anthracene; benzene), esp. those of the alkene series (butylene)
