qüestioni
"Qüestioni" is not a standard word in Catalan. It may be a conjugation or misspelling.
Here 'qüestioni' is used as a subjunctive verb in the second person singular, indicating a polite or formal command to not question something.
No qüestioni les meves decisions.
Don't question my decisions.
In this sentence, 'qüestioni' is in the present subjunctive and indicates a hypothetical or desired action that the subject should perform.
És important que qüestioni les seves opcions abans de decidir.
It's important that he/she questions his/her options before deciding.
Here, 'qüestioni' again works as a subjunctive, used in a directive form to stress the condition for questioning.
