既得権の適用除外
解説 Definition
既存のものや既得権に対して、新しい規則の適用を除外する政策。新規制が施行される際に、経過措置として利用され、急激な変化の影響を緩和する。
Grandfathering is the practice of allowing people or organizations to keep following an old rule even after a new rule has been introduced. It is often used in law, business, and government policy when existing cases are given special permission to continue.
覚え方のコツ Memory Tip
grandfathering は grandfather clause とセットで覚えると残りやすい。新ルールができても、前からいる人・前から使っているものはそのまま扱う、という「既存組だけ旧条件のまま」の発想。法律・制度・契約・料金改定でよく出て、grandfathered users / existing customers are grandfathered in の形が頻出。全面免除ではなく、新規参加者には新基準、既存者には例外という線引きが核心。legacy と近いが、こちらは単に古いのでなく、新制度から意図的に外す点を意識。
Remember it with `grandfather clause`. The image is: a new rule starts, but older users, customers, or systems keep the old treatment. Phrases like `grandfathered in` or `grandfathered users` are common, so connect the word with an exception for existing cases.

grandfathering の語源・成り立ち Etymology
grandfatheringはgrandfather＋-ingで、grandはラテン語grandis系、fatherは古英語faederにさかのぼります。関連語はgrandfathered、forefather。新ルールでも「祖父の代からの人は除外」という発想が、既得権維持の意味を生んでいます。
Grandfathering comes from grandfather plus the ending -ing. Grand goes back to Latin grandis, meaning "large" or "great," and father comes from Old English faeder. The modern sense grew from the idea that people with older rights or status were allowed to stay outside a new rule. In other words, people were treated as if they were protected from an earlier generation.
