The etymology of the phrase "greased lightning" can be traced back to the combination of "grease" and "lightning".
1. Grease: The word "grease" comes from the Old French word "grece" which means "rendered fat" or "lard". It originated from the Latin word "crassus" meaning "thick, solid, or dense". Over time, "grease" came to refer to any oily or fatty substance used for lubrication.
2. Lightning: The term "lightning" is derived from the Old English word "lighten" or "lightnen", meaning "to make bright or shed light". It ultimately stems from the Proto-Germanic word "linhtinaz", which has the same meaning. "Lightning" refers to the bright flashes of light that appear during a thunderstorm.
