inexorable
adjective

- not able to be stopped or changed

Merriam-Webster Dictionary

Coming from Middle French and Latin the word exorable contains "ex (out)" + "orare (to pray)", so it refers to events that can be influenced through prayer or pleading.

Inexorable refers to the opposite status. Nothing that you say or do will change the situation.

People can be inexorable, too. They cannot be made to change their mind. And yet, we still try. Consider these expressions the next time you attempt the impossible with the inexorable:

- blue in the face = for a long time (I reasoned with her till I was blue in the face, but she wouldn’t sign that document)

- till the cows come home = for a long but indefinite time (I won’t say I’m sorry! You can wait for my apology till the cows come home)

- trying to get blood out of a stone = an unsuccessful attempt (Getting Sarah to agree is like trying to get blood out of a stone)

- flogging a dead horse = a useless attempt (Trying to convince him is like flogging a dead horse)
