Inflexión · RCI
A Spanish-grammar esoteric programming language.
Inflexión is a hand-built esoteric programming language whose semantics flow from the grammatical features of Rioplatense Argentine Spanish. Spanish’s two copulas (ser for essential properties, estar for transient state) map to immutable and mutable bindings; verbal mood (indicative, subjunctive, imperative) maps to evaluation strategy (eager, deferred, effect); aspect (perfective, imperfective) maps to eager and lazy on the same operation; the fixed-order Spanish clitic system maps to positional argument routing; productive diminutive and augmentative morphology maps to numeric and computational scaling; number agreement carries the scalar versus collection distinction.
Inflexión joins a small lineage of inflection-driven non-English natural-language esoteric programming languages, Perligata (Latin, Damian Conway, 2000), Espro (Esperanto, 2015, idea-only), Tampio (Finnish, Iikka Hauhio, ~2017 to present), Wenyan (Classical Chinese, Lingdong Huang, 2019), Inflexión(Rioplatense Spanish, 2026), and is the first in that lineage to use a living Romance language and the first to make this specific feature set jointly load-bearing. It is hand-built rather than generated by Babel, the companion methodology, so that the language design is not constrained by what Babel’s parameter schema can currently express.
This is the project’s public landing page. The runtime ships as version 0.0.11 with twenty example programs running through the public playground at babel.roderickc.com. The design paper (Installment 1) describes the six grammatical-semantic mappings; the operational-semantics paper (Installment 2) formalises what the runtime does, with big-step evaluation rules and a worked Brainfuck interpreter as the Turing-completeness witness. Both are linked below.
Playground, Try the runtime in your browser ↗
A live web playground for the Babel runtime, which Inflexión will ride on once its parser ships. Today: vanilla Brainfuck and Rioplatense-Spanish Brainfuck both run end-to-end. Inflexión proper is a 'coming soon' tab for now.
Inflexión, White Paper (Installment 1: Design)
The first-installment design paper. Six grammatical-semantic mappings (number, mood, aspect, ser/estar, clitics, diminutives), the dialect choice and its rationale, four worked examples, the Turing-completeness argument, the LLM-prompting-density hypothesis stated as such, and a naming coda. Hand-built; not generated by Babel.
Inflexión, Operational Semantics (Installment 2)
The formal companion to the design paper. Lexer (spaCy + custom Spanish-morphology rules), grammar (extended BNF), abstract machine (environments, cells, two binding kinds), and big-step evaluation rules for each of the six mappings plus the control-flow, data, and I/O extensions. Turing-completeness via a worked Brainfuck interpreter; dynamic type discipline; runtime error model.
Babel, Companion Methodology
The companion methodology paper for the programmatic construction of esoteric programming languages. Inflexión is one specific instantiation of the design space Babel opens, deliberately hand-built so the design is not constrained by what Babel's parameter schema can currently express. Lives at /babel.
Articles, The Long-Form Series
A LinkedIn-syndicated essay series on the impact of language in technology. Three articles published; the third is the lineage-discovery story that situates Inflexión among Perligata, Espro, Tampio, and Wenyan. Lives under /babel/articles since the series is published from the Babel project's perspective.
Authored by Ramon Rodriguez under the auspices of RCI. The dialect-comparison work in particular would benefit from co-authors whose native dialect is neither Rioplatense nor Venezuelan. Source code (when the interpreter ships) at github.com/Roderick-Consulting-Inc.
