If you meant to type "Posserus" but misspelled it, here are some possible correct suggestions: "Possess", referring to ownership; "Poser", meaning someone who pretends to be something they're not; "Poses", which are different positions used in yoga or modeling; "Persist", indicating determined effort; or "Poserous", a word that doesn't exist but could be interpreted as a mix between "poser" and "prosperous".
