Euclidese

Euclidese is a fictional constructed language designed to encode Euclidean geometric reasoning. It features in speculative fiction and linguistic exercises as a tool to explore how geometric ideas might shape grammar, vocabulary, and argument structure.

Origins and use: Developed by a collaborative of linguists and writers in the early 21st century, Euclidese has no native community and is primarily used in world-building, language-creation projects, and instructional demonstrations.

Phonology and writing: The phonology comprises five vowels and a moderate consonant inventory, with syllables typically CV or CVC and predictable stress on the penultimate syllable. It is usually written with a Latin-based alphabet, though some projects employ a set of geometric glyphs to mark noun classes and grammatical relations.

Grammar and morphology: Euclidese uses an agglutinative morphology. Nouns are organized into shape-based classes such as point, line, plane, and solid, which affect derivation and agreement. Spatial relations are expressed with postpositions that encode in, on, between, and around. The basic word order is subject–verb–object, with frequent topic-comment and hypotactic constructions. Verbs encode aspect and proof direction, reflecting geometric reasoning with markings for deduction, hypothesis, and conclusion.

Lexicon and sample: Core vocabulary derives from geometric terms and their abstractions; numeric and temporal terms are regularized by simple affixes. A representative, non-narrative sentence is Tria linea in plano, meaning Three lines in the plane. Euclidese emphasizes precision and logical clarity, mirroring an axiomatic approach to discourse.
