Isimleir

Isimleir is a theoretical construct in linguistics and onomastics used to describe the rules and patterns governing the formation, modification, and use of names within a language or constructed language. It covers name derivation and compounding, phonotactic constraints on name shapes, inflectional paradigms for cases and numbers, and the semantic functions of names in social and textual contexts. Practically, isimleir provides a framework for analyzing how names—given, place, and ethnonyms—are created and adapted to different grammatical environments and how they signal identity and culture.

Isimleir is a neologism created for explanatory or worldbuilding purposes. It is not an established term in mainstream linguistics, and its precise definitions vary by project. Because it often appears in speculative grammars for fictional languages, its rules are typically described locally rather than universally accepted.

Core components of isimleir include a base stem, a set of productive affixes for derivation and inflection, phonotactic rules that constrain permissible name shapes, and semantic modules that map names to social meanings such as formality, kinship, or geographic origin. Name formation may involve derivation from common nouns, compounding of smaller name elements, or affixation to generate derivative forms.

Examples (fictional): In the isimleir system, the base name Aren yields the genitive Arenos and the diminutive Arenik. The placename Val yields the adjectival demonym Valaran and the plural Valarar for nearby districts. A compound given name Sol + Dar forms Soldar as a full personal name. These patterns illustrate how a single base can support multiple name types through consistent rules.

Applications include linguistic theory, conworldbuilding, and the study of how naming systems reflect social structure. Limitations include its speculative status and variability across projects; readers should treat isimleir as a theoretical or fictional construct rather than a real-world standard. Related concepts include onomastics, anthroponymy, morphology, phonology, and language construction.
