coherency

The word 'coherency' has a tangible, physical origin. It stems from the Latin verb 'cohaerēre,' meaning "to stick together, be connected," which itself is a compound of the prefix 'co-' (together) and 'haerēre' (to stick). This literal sense of physical adhesion evolved logically into the abstract idea of logical connection and consistency. Over time, the suffix '-entia' (yielding '-ency' in English) was added to form a noun describing the state or quality of being stuck together, which we now understand as clarity, unity, and logical interconnection.
