Etymology: Octopod is a compound of two Greek roots, and its most telling feature is the detour it took through taxonomy. The "octo-" part comes from Ancient Greek "oktō," meaning "eight," the same root behind "octave" and "October," which was the eighth month in the old Roman calendar. The "-pod" part comes from Greek "pous," meaning "foot," so the word literally describes an eight-footed creature. The name was not coined to describe everyday sea life. It was formed after the taxonomic name "Octopoda," the scientific order that groups octopuses, and it became a general English word for an eight-legged animal in that scientific setting. Its relationship to other English words is a neat one: it is a "piecewise doublet" of "octopede" and "octopus," meaning it shares its sense and pieces with those words but was assembled separately, so the three are close relatives rather than one descending from another.
