      Octopuses is correct if you’re referring to many different species of octopus. Octopi would be correct if you’re referring to a cluster of one species of octopus.

        Then the meme is formatted incorrectly. Or “correctly”, if we define correct as “incorrect, but, you get it, so…”

          Except, usage defines language. If it didn’t, English wouldn’t exist. Therefore, usage is correct when people understand and use it.

      The Latin origin. Words ending on -us turn almost always into -i in plural in Latin. And that’s where it comes from (octo eight, pus/pes foot).
