The word “inherence” originates from a latin word “inhaereo”. It is interesting that this word means both “cleave, split” and “stick, adhere”. It indicates that there are at least two distinct parts that are strongly connected and forming one whole. So even if those two components are separate, they cannot function separately without each other.
The dictionary of philosophy defines “inherence” as “the relation of an attribute to its subject.” For example, blowing is an inherent attribute of wind. Wind can’t exist without blowing. And when air moves (blows) we call it wind.
It is a state of inhering, permanent existence in something; innateness; inseparable and essential connection; permanently present in something; indwelling.
