Inherent
Etymology
From Latin “inhaerere,” to stick in or cling to, from “in-” and “haerere,” to stick (the same root as “adhere” and “cohere”). What is inherent clings to a thing so closely it cannot be peeled off.
adjective · /in-HAIR-uhnt/
Existing in something as a permanent, inseparable part of its nature.
What it names
A quality you cannot remove without destroying the thing — a built-in feature, not an added one.
Example
There is an inherent tension in the role: you must both defend the team and judge it.
Related idea
What is inherent is inseparable from a thing; what is intrinsic belongs to it by its own nature; what is extrinsic comes from outside. Inherent stresses that it cannot be removed, intrinsic that it is essential.
