Origin and Etymology of antlia
borrowed from New Latin Antlia (Pneumatica), literally, “(air) pump,” going back to Latin, “means of drawing water, treadmill,” borrowed from Greek antlía “hold of a ship, bilgewater, reservoir,” derivative of ántlos with same sense, perhaps derivative (with an instrumental suffix -tlos dissimilated from *-thlos) of an Indo-European verbal base *h2en- “draw (water),” whence Hittite han- “draw (water)”
