Erund

Erund is a term used in some linguistic discussions and worldbuilding contexts to signify a particular type of verbal noun formed from a verb by a nominalizing suffix, commonly -erund. In this use, erunds are treated as nouns that encode the action or process of the verb while remaining distinct from finite verb forms. Erund is not a universally adopted term in mainstream descriptive linguistics and is often presented as a theoretical or constructed-language concept rather than a widely attested grammatical category.

Morphology and syntax

Erunds are typically described as being created by attaching a suffix such as -erund to a verb stem. Phonological adjustments may accompany this derivation in different theoretical accounts. As nouns, erunds can participate in noun-like syntax: they may be preceded by determiners, modified by adjectives, and appear as subjects or objects of clauses. In many frameworks, erunds do not bear tense and do not inflect for subject agreement, though some theories allow limited morphophonemic alternations or case marking when placed in particular syntactic positions.

Semantics and usage

The semantic focus of erunds is the action or process denoted by the original verb, treated as an abstract or generalized event rather than as a concrete predicate. This contrasts with some uses of gerunds in natural languages, where the line between action concepts and noun-like reference can be blurry. In constructed languages or theoretical models, erunds may also be used to encode habitual or repeated actions, depending on the design of the grammar.

Relationship to related forms

Erund is related to verbal noun and gerund concepts but is presented as a separate, theory-dependent category. Some grammars view erunds as a distinct nominalization with specific distributional properties, while others treat them as an alternative naming for a broadly similar phenomenon. In literature and worldbuilding, erunds are often used to explore differences between action-noun and event-noun constructions without claiming universal linguistic reality.
