Hang around a know-it-all long enough and eventually, you will hear someone corrected when they try to talk about more than one octopus. Many people think the right plural form is 'octopi' but based on the Greek roots, it technically should be 'octopodes.' No one says that, however, so grammarians have settled on 'octopuses' as the correct pluralization of octopus. Yep, it's exactly what you always thought it was! As for 'octopi?' It's not even a word.
