Etymology
The word 'adherence' originates from the Latin verb adhaerēre, a compound of ad- ("to") and haerēre ("to stick"). The core concept is one of physical attachment, as if glued or fastened to something. Over time, this literal sense of sticking was metaphorically extended to describe abstract forms of attachment, such as faithfully following a set of rules, principles, or a prescribed course of action. The suffix -entia (later becoming -ence) was added to form the noun denoting the state or quality of being firmly attached or devoted.
