Even if the dictionaries are starting to give in, I refuse to accept 'octopi' as a word mainly because--I'm not making this up--there's
a really satisfying climactic scene in the Orson Scott Card horror novel 'Lost Boys' which hinges on it being an incorrect pluralization.
I'm with you (for different reasons!). 'Octopi' is just /wrong/. The root word is Greek, not Latin!
The Chambers Dictionary 11th edition also states: "octopi is wrong"
octopodae
en.wikipedia first correctly writes Octopoda, to in the next sentence go on with Octopuses ...
Octopoda is the biological order
how do you feel about *mongeese*?
why can't octopus be plural and singular, like fishes or sheeps?
i still think the plural of house should be hice
and the plural of moose should be meese, obviously.
either that or just dispense with the arcane spellings and pluralize things just like the rest of the freaking english language.
