The Origin of Possess or Posess

The correct word possess comes from Latin possidere, meaning to own or occupy. Over time, this became possess in Middle English.

The double “ss” spelling stayed because of pronunciation and historical spelling rules. English often keeps double consonants from Latin roots to preserve sound clarity.

Posess never existed historically—it is simply a modern spelling mistake caused by typing fast or misunderstanding double-letter rules.
