Grandfathered is a term used to describe a situation where an older rule or regulation is still in effect even after a new rule or regulation has been established. There are several synonyms that can be used in place of grandfathered, such as exempted, grandfather clause, protected, or pre-existing. Exempted implies that certain individuals or entities are excluded from the effects of a specific rule or regulation. Grandfather clause refers to a condition that allows certain individuals to be exempt from a new law or policy based on their previous status. Finally, pre-existing means that something was already in existence prior to the implementation of a new policy or rule.
