"Obeisant" Natural Recordings by Native Speakers
Obeisant refers to being courteous, respectful, or submissive, often in a way that is overly flattering or obsequious. It can also describe a gesture or action that shows deference or humility, such as bowing or kneeling. A person who is obeisant is one who shows a willingness to obey or show respect to a higher authority or superior.
I apologize, but there is no word called "obedientiary". It's possible that you meant to type "obituary", which is a notice of someone's death, usually written by a newspaper or published online.
