Forms
octōpūs m (genitive octōpodis); third declension[1] The TLL gives it as of common gender, with a nominative octopoda in Alexander of Tralles.[2]
Etymology
It is borrowed from Ancient Greek ὀκτώπους (oktṓpous, “eight-footed”),[1][3][2] from ὀκτώ (oktṓ, “eight”) and πούς (poús, “foot”).[1][3] The TLL compares octipēs “eight-footed”, formed in Latin itself.[2]
Earliest recorded meaning
The TLL's first witness is Pliny Valerianus, who uses it of the squid (lolligo) as the creature with eight feet.[2]
Semantic evolution
In Late Latin it was rare: the Latin Alexander of Tralles has the nominative octopoda.[2] In New Latin it became the name of the octopus itself.[1]
