Etymology: The concept captured by this noun is formed by layering English prefixes and suffixes onto a root word with Latin origins. At its core lies "concurrent," which entered English in the mid-17th century from the Latin "concurrere," meaning "to run together." This Latin verb combines "con-" (together) and "currere" (to run), originally conveying the idea of things happening or moving simultaneously. Adding the prefix "non-" negates this simultaneity, marking the absence of concurrency. "Non-" itself is a straightforward Latin negation used in English since the Middle Ages. The suffix "-ency," derived via Old French from Latin "-entia," forms abstract nouns indicating a state or quality—in this case, the quality of happening at the same time. Putting these parts together, the noun denotes the state or condition of events or processes not occurring simultaneously. The term is relatively modern, likely coined in technical or academic contexts where precise descriptions of timing are necessary, such as computer science, law, or philosophy. Its construction follows a predictable pattern of English word formation but serves a specialized semantic purpose. While "concurrency" has been established for centuries, "nonconcurrency" emerged as a necessary counterpart to describe systems or events explicitly lacking simultaneous occurrence. This term reflects the ongoing expansion of English vocabulary through systematic morphological processes to meet new conceptual needs.
