How to Spell Possession can be tricky because it contains double letters and an ending that is easy to mix up. The correct spelling is possession, with ss in the middle and ss before the final ion. Learning a simple spelling pattern and practicing the word in sentences can help you remember it confidently.
Why Possession Is Hard to Spell
The word possession is difficult to spell because it contains several letters that are easy to mix up. Many people forget one of the double s letters or accidentally write possesion instead of possession. The repeated sounds can also make it harder to remember exactly where each letter belongs.
Another challenge is remembering how the word is formed from possess. When -ion is added, the spelling keeps the double s, giving us possession. Breaking the word into smaller parts, pos + sess + ion, makes its spelling easier to see and remember.

Possession Spelling Breakdown
The correct spelling is possession. You can break it into three simple parts: pos + sess + ion. The key is to remember the double s in sess and another s before ion.
Possession = pos + sess + ion
- pos → the beginning of the word
- sess → contains the important double ss
- ion → the common ending
A useful way to remember it is: possess + ion = possession. This helps you keep the correct spelling instead of writing possesion or posession.
Word Origin
The word possession comes from the Latin word possessio, meaning ownership or the act of possessing something. It entered English through Old French and developed into the modern spelling possession. The word is related to possess, which comes from the Latin possidere, meaning to own or have control of something.
Knowing its origin can also help explain why possession keeps the double s. The connection with possess gives you a useful spelling clue: possess + ion = possession.
Memory Trick for Possession
A simple way to remember possession is to think: “Possess something, then add ion.” Start with possess, which already has double ss, and add -ion to make possession. This gives you the correct spelling without having to memorize every letter separately.
Memory trick:
POSSESS + ION = POSSESSION
Remember: pos + sess + ion. The word has three s’s in total, making it easier to spot the correct spelling.
