logy

Based on surface resemblance, you might guess that "logy" (also sometimes spelled "loggy") is related to "groggy," but that's not the case. "Groggy" ultimately comes from "Old Grog," the nickname of an English admiral who was notorious for his cloak made of a fabric called grogram - and for adding water to his crew's rum. The sailors called the rum mixture "grog" after the admiral. Because of the effect of grog, "groggy" came to mean "weak and unsteady on the feet or in action." No one is really sure about the origin of "logy," but experts speculate that it comes from the Dutch word log, meaning "heavy." Its first recorded use in English, from an 1847 London newspaper, refers to a "loggy stroke" in rowing.
