Today, I made a new word-"mostvalic".

Mostvalic (adj.) Describes something or someone that holds the highest personal value or meaning — beyond logic, beyond trend. It’s not just important, it’s irreplaceably significant to your soul.

Example: “That moment under the stars was the mostvalic part of my whole year.” “She’s not perfect, but she’s mostvalic to me.”

Let me know any if you have ever stumbled upon your own lexicon.
