The word posses is not another spelling of possess.
Instead, posses is simply the plural of posse.
A posse is a group of people gathered for a specific purpose, especially to help law enforcement search for someone or maintain order.

Possess vs Posses: Key Difference
| Feature | Possess | Posses |
|---|---|---|
| Part of Speech | Verb | Plural noun |
| Meaning | To own or have something | More than one posse |
| Common Usage | Very common | Rare |
| Correct in everyday writing | Yes | Only in specific contexts |
| Example | I possess confidence. | Two posses joined the search. |
The biggest difference is that possess expresses ownership or having something, while posses refers to multiple groups of people.
Why Do People Confuse Possess and Posses?
The confusion happens because the words differ by only one letter.
Many English learners assume removing one “s” doesn’t change the meaning. However, English spelling often distinguishes completely different words through small letter changes.
Other reasons include:
- Similar pronunciation
- Typing errors
- Autocorrect mistakes
- Limited familiarity with the noun posse
Fortunately, remembering one simple rule makes the distinction easy.
Easy Trick to Remember the Difference
Think of it this way:
Possess has two “s” letters at the end because ownership is something you want to keep complete.
Meanwhile:
Posses = multiple posse groups.
If you’re talking about owning, having, controlling, or holding something, always use possess.
