cohaerens

Cohaerens is a Latin term meaning "holding together" or "cohering." In scholarly contexts it has been used to describe relations of coherence within a system of concepts, definitions, or arguments, emphasizing how parts fit together in a mutually supportive way. The present participle form cohaerens (and the related noun cohaerentia) appears in medieval and early modern Latin writings to articulate the idea that certain elements of a definition or proposition are tied together by a consistent, interconnected structure.

Etymology and usage. The word derives from the prefix co- (together) and haerere (to cling or adhere). In philosophy and logic, cohaerentia was used to discuss how universal terms, species, and their predicates relate within a given account. A cohaerent argument would be one in which the premises and conclusions remain in logical alignment, with components that reinforce rather than contradict one another. Over time, the term has largely fallen out of everyday use, superseded by more common terms such as coherence, consistency, and logical compatibility.

Modern relevance. Today, cohaerens is rarely employed outside historical or philological discourse. In contemporary philosophy and linguistics, descriptions of coherence tend to rely on standard notions of logical consistency, semantic fit, or discourse-level cohesion rather than the Latin terminology. There is no widely recognized scientific taxon or formal category named Cohaerens in current biological, chemical, or astronomical nomenclature. If encountered, the term is typically encountered in discussions of historical theory, rather than as a present-day technical label.
