óskrifaða
Óskrifaða is an Icelandic word that translates to "unwritten" or "undocumented." It is often used in a figurative sense to describe something that has not been formally recorded, established, or agreed upon, even if it is understood or practiced. This can apply to various aspects of life, from social customs and traditions to unwritten rules within a community or organization.
For instance, an óskrifaða law might refer to a customary practice that is followed without being codified
