Well, we can't have all the octopodes nuts having their secret octopodes (related?) discussions with their own secret language like the word "octopods", now can we?

We can't keep letting them get away with it!

I feel like any linguist upset by non-prescriptive language needs to maybe reconsider their life choices. Imagine telling someone they're painting incorrectly or being mad at the discovery of a new species.

Octopi, octopuses, and octopods are all valid pluralizations of octopus in American English.

Conversely, cacti is the only valid pluralization of cactus.

Don’t worry, language itself pissed us off long before you did.

Linguists are probably the least likely people to get upset at someone using the "wrong" word. they might pull out their notebook and start asking you questions though
