Ever notice how people say “opossum” and that first “o” just kind of vanishes? It feels odd since the word starts with an “o” on paper.
Technically, the “o” in opossum is there, but most folks skip it in regular conversation, making it sound like “possum.” You’ll hear this all over the U.S.
The whole silent (or soft) “o” thing goes way back. Native American languages gave us the word, and over time, people changed how they said it before anyone bothered to update the spelling.
So, if you say “opossum” and pronounce the “o,” or just “possum,” you’re not wrong either way. Both are totally accepted.
Ever wondered why it sounds like that? There’s a little story behind it.
If you’ve heard people debate whether the “o” is really silent, you’re definitely not alone. Different places and sources have their own take, but knowing a bit of history helps make sense of it.

Why the ‘O’ Is Considered Silent in ‘Opossum’
People say the “O” in opossum is silent because that’s just how it sounds when they talk. This comes down to the word’s origins, how it rolls off the tongue, and even which country you’re in.
Common Pronunciation Practices
You’ll hear folks say opossum as “uh-possum” or just “possum.” When they drop the first “O,” it really does seem silent.
In America, that’s especially common in casual conversation. Some dictionaries insist you should pronounce the “O,” but honestly, most people don’t bother.
That’s why possum pops up everywhere instead of opossum. Both work, but “possum” just feels easier.
People stick with “possum” because it’s simple. The two words sound so close that it’s no wonder the “O” gets ignored, even if it’s technically there.
Origins of the Word ‘Opossum’
The word opossum came from the Algonquian Native American word aposoum, which meant “white animal” or “white dog.” English speakers picked it up and, well, changed how they said it.
As they tried to pronounce it, the “O” sound got softer or disappeared in everyday speech. That’s why so many Americans say it the way they do now.
The spelling kept the “O,” but the way people say it just drifted. So, you see the letter but might not hear it much.
Differences in American and Australian Usage
In the U.S., people usually say possum and leave out the “O.” Here, opossum means a specific North American animal.
In Australia and New Zealand, possum points to different animals. Aussies almost never pronounce the “O.”
These regional quirks make things confusing sometimes. But in the U.S., people often drop the “O” in regular speech.
You can say it either way, and folks will get what you mean depending on where you are.

Linguistic Background and Animal Classification
The word “opossum” has a wild history rooted in Native American languages and animal science. Knowing where it comes from helps you see why people often drop the “o” in speech.
You’ll also notice how two different marsupials ended up with similar names, even though they’re not close relatives.
Algonquian Roots and Historical Spellings
“opossum” comes from a Virginia Algonquian language. Back then, it meant “white dog” or “small animal.”
Early English settlers spelled it all sorts of ways—apossoun, opassom, and so on.
As time went by, people started dropping the “o” in casual talk. Linguists call this aphesis—it’s when you lose an unstressed vowel at the start of a word.
That’s why you hear “possum” instead of “opossum” so often.
Language just changes like that, especially when people borrow words from other cultures. It’s pretty cool to see how the “o” in “opossum” faded out in speech but stuck around in writing.
Opossum vs Possum: Marsupials Explained
The words “possum” and “opossum” trip people up because they sound alike but mean different animals, depending on where you are.
In North America, the Virginia opossum is the only marsupial you’ll spot. Folks usually call it “possum” just to keep things simple.
Australian possums? Totally different animals. They mostly live in trees and belong to species you won’t find in America.
Even though the names are similar, these animals took separate evolutionary paths.
Just remember: “opossum” is usually the North American critter, while “possum” is what Australians call their tree-dwelling marsupials.
Family Differences: Phalangeridae and Didelphidae
The family Didelphidae covers American opossums, like the Virginia opossum. You’ll find these marsupials hanging out on the ground, using their opposable thumbs and gripping tails to get around.
Australian possums? They fall under Phalangeridae. These guys usually stick to the trees, have softer fur, and their bodies just look and feel different.
Here’s a quick comparison:
| Feature | Didelphidae (Opossums) | Phalangeridae (Possums) |
|---|---|---|
| Location | North and South America | Australia, New Guinea |
| Habitat | Ground-based | Tree-dwelling |
| Tail | Prehensile (gripping) | Often bushy and furry |
| Size | Medium | Small to medium |
When you look at these families side by side, it’s easier to see why people mix up the names. The whole “opossum” vs. “possum” debate actually makes more sense with this background.
