Words brought into English can use English pluralisations, so you’re not wrong if you say octopuses. I think Grammar Girl had a take on this maybe 7 or even 8 years ago by now. These days, I can’t see myself getting worked up about it for the sheer fun of being pedantic like I used to.
It’s not octopuses that octopodes corrects, it’s octopi. Octopi is a Latin pluralization, and since the word is Greek and us to i isn’t specifically American, I agree with you that octopuses is fine but not that octopi is fine.
Octopi is also correct. If anything, more correct than octopodes by virtue of popularity. Mismatching the language to the suffix does not a fake word make!
If you want a hyper anglizism: I’m German and after an interview, a colleague of mine talked about the candidates’ “vibes”. My boss didn’t get it’s English and once she did, she pronounced it like “wipes”. b>p at the end of words is what German always does and v>w to make it sound English since German has the /v/ sound but not /w/. I don’t think it’s a common thing tho.
The word octopus is a classical Greek word that comes to English via Latin. The Greek plural is octopodes, the Latin plural is octopi. But we don’t speak Latin or classical Greek. We speak English. Because octopus is the English word for octopus it follows the English rules for pluralization, which is to add “s” or “es” to the end of the word. Cases can be made why octopi and octopodes could be technically correct, but for English speakers octopuses is the most correct.
Yeah, I did something for work where I had to study up about it and instead of being angry it’s just kind of a fun fact. I don’t actually mind what people say, I think everyone understands what you mean regardless.
