The best word to replace "inherent" in the context of the expression "original sin" is inherent. Original sin refers to the idea that the sinfulness of Adam and Eve's actions is a fundamental aspect of human nature, implying that it is intrinsic or innate within every human.
Here's how it fits:
- Inherent: This captures the idea that sinfulness is an intrinsic part of being human, rooted in the original sin story.
The other options (accidental, incidental, external) do not convey the same meaning in this context.
