Simplified etymology

Octopus, recorded from the mid-18th century, comes from Greek oktōpous, formed from oktō, “eight,” and pous, “foot.” The name therefore means “eight-footed.”

Etymology

From scientific Latin octopus, from Greek oktōpous, formed from oktō, 'eight,' + pous, 'foot.' The original compound therefore means 'eight-footed.' The historically regular plural is octopuses; octopi arose later from a mistaken Latin-style analysis.
