AgentenSuffix

AgentenSuffix is a term used in linguistics and constructed language design to describe a hypothetical suffix that forms agent nouns from verbal roots. The suffix is designed to encode agency, signaling that the base verb's action is performed by a person or entity rather than the result or instrument of the action.

Formation and rules: The AgentenSuffix attaches to the verb stem with minimal phonological alteration. In proposed systems, it may require mild vowel adjustments to fit phonotactics, but generally keeps the stem recognizable. The resulting word denotes an agent—someone who performs the action. In some languages, additional plural or definite marking may be added to reflect number or reference.

Examples: cook + -en = cooken (one who cooks); write + -en = writen (one who writes); study + -en = studyen (one who studies). In many theoretical descriptions, orthography and phonology are chosen to maintain readability and compatibility with the language’s overall sound system.

Context and use: In conlangs and linguistic theory, the AgentenSuffix offers a unified way to derive agent nouns across verb classes. Critics note that agentive derivation in natural languages is typically irregular and composite, with multiple suffixes and allomorphs. As a theoretical device, the suffix provides a concrete mechanism for exploring how agency is encoded morphologically and how it interacts with syntax and semantics.

Related concepts include agentive nouns and derivational morphology more broadly.
