And of course rhinoceri
the plural for rhinoceros is either unchanged ("wow, look at all those rhinoceros") or with your standard es ending: "Let's go see some rhinoceroses. the "i" plural is only found in words that end with "us".
additionally, the "i" ending for plurals are reserved for Latin words(or more precisely, words derived from latin words) in the second declension, in the nominative singular. Common words that are mis-pluralized include examples such as virus- the proper plural is viruses, not virii, since the word virus comes from the latin vīrus, which means basically "poison". Because it denotes something uncountable, it is therefore a mass noun, like homework, blood, food, luggage, trash, etc whereby there really is no plural, and in cases where one would expect a plural you instead use the standard mass noun (thus the name). Even Octopi is not strictly correct, and results from the misunderstanding that Octopus is a second declension latin noun, which it is not. (therefore the proper term is octopuses).
Bear, is of course, pluralizes using the standard s ending, for example:
bears
I shoulda said "quandry of Bears".....
Then i woulda covered all bases.
If you have a large group of bears, you might use the Congregational term "sloth" which denotes a group of bears. Or maybe it's a bear congress. That would be funny to see. Sloth of bears in a big parliament type building debating and wearing suits and glasses, debating a new bill prohibiting porridge sampling. Why would they come up with congregational terms for animals that hardly ever get together(as far as humans know) is rather beyond me. on an unrelated note, I'd like to point out that it's odd how we can dictate names for all young kangaroos and opossums. I think their mothers should have some say, and who decided they should all be called Joey anyway? He was the most annoying character in friends, and when the *censored* did we start coming up with scientific-type terms based on television sitcoms that ran for about 5 years too long? What's next, will a group of divorced Albino Polar Bears be called a Monica? Will we start referring to large groups of Chochke collecting penguins as a Marge Simpson?
NO! I'm putting my foot down! it ends here!
Now, back to the topic at hand, which If I recall was bears. Or perhaps Rhinoceroses, which I like to think of as Wine and Waxy roses. Wax coming from Cera, of course.
