Etymology
The word 'adhesion' has a clear and logical journey from physical attachment to abstract commitment. It originates from the Latin verb adhaerēre, itself a compound of the prefix ad- ("to") and the verb haerēre ("to stick"). The core concept of "sticking to" something was preserved as the term entered Middle English via Old French. Over time, its application broadened from describing the physical sticking together of materials to encompass medical conditions where tissues stick abnormally and, finally, to the figurative sense of steadfast loyalty or attachment to an idea.
