Taxonomy of "-on" Units in Linguistics and Semiotics

These terms are mostly non-standard or theoretical, using the suffix "-on" (from Greek -ον) to indicate atomic or indivisible units of structure, meaning, or function.

I. Linguistic Units

• Morpheon: Proposed atomic morphological unit (rare usage)
• Lexon: Unit of lexical relation in semantic networks (e.g., Gellish)
• Glosson: Hypothetical sign unit in Glossematics (Louis Hjelmslev)

II. Phonetic / Acoustic Units

• Phonon: Borrowed from physics; metaphorical for smallest unit of sound (non-standard in linguistics)

III. Semantic / Cognitive Units

• Semion: Minimal unit of meaning (conceptual, rare in usage)
• Noeton: A unit of thought or cognition (from noesis, used in philosophical linguistics)
• Actemeon: Proposed action unit in speech/discourse (experimental)

IV. Narrative / Structural Units

• Narraton: Proposed minimal unit of narrative structure (used in semiotics/narratology)

V. Cognitive Modeling / AI

• Perceptron: Neural processing unit (standard in AI; used in modeling cognitive linguistics)
