wesanbeon

Wesanbeon is a term used in comparative Germanic linguistics to describe the hypothesized dual existence of two copular verb stems meaning "to be" in the ancestor language of West Germanic languages. The term combines wesan and beon, two Old English verbs that historically functioned as the core of the language’s copula system. Wesanbeon is a modern scholarly label used to discuss how these stems might have coexisted, overlapped in distribution, and gradually merged into the single modern English be.

Etymology and scope: The label derives from wesan and beon and is used specifically in discussions of historical syntax and morphology of the be-verb. It does not reflect a separate, attested language term but a theoretical construct in reconstructions of Proto-West Germanic.

Concept and usage: In the proposed view, wesan corresponds to be-stem usage in particular grammatical environments (for instance, certain tenses or moods), while beon covers another set of contexts. The two forms were later unified through sound change, analogy, and simplification across dialects.

Limitations: The idea remains a topic of debate. Some scholars argue for alternative explanations such as gradual regularization of multiple be-forms into a single paradigm, rather than a clean bifurcation.
