Do You Know The Correct Plural Form Of "Octopus"?

We got the deets from the experts.

As far as eight-legged creatures go, the octopus pretty much reigns supreme. But what happens when you have more than one octopus? What is the plural of "octopus"?

While talking to Monterey Bay Aquarium aquarists Chris Payne, Alicia Bitondo, and Bret Grasse about another post, I asked them which plural form of "octopus" is the right one, "octopi" or "octopuses."

Their expert brains told me that the most correct form was "octopuses," so problem solved, right????

I mean, they would know, they are the OCTOPUS EXPERTS.

Except that some people in the comments highlighted a whole new plural form I've never heard of: "octopodes."

So I went back to Chris Payne, Alicia Bitondo, and Bret Grasse, who told me that while "octopodes" is technically fine, the best plural form is still "octopuses."

"Octopodes" is fine because the root of "octopus" is Greek, like "octopuses." "Octopuses" is better because it's the most common English plural form.

"Octopi," however, is a Latin form, and therefore totally incorrect. Chris Payne lamented the use of "octopi" because "unfortunately ... it just 'sounds' correct."

Even our own BuzzFeed copy editors weighed in on the "octopodes" vs. "octopuses" debate.

Note from our copy chief: "Octopi" is an accepted variant in the dictionary but mainly because it falls into the category of "words people use incorrectly so often that they wind up in the dictionary after a while."

So it's STILL "octopuses," OKAY???

  1. So let's settle this once and for all. What is the most correct plural form of "octopus"????
