meaningsplit

Meaningsplit is a term used in linguistics and philosophy of language to describe a phenomenon in which a single linguistic form yields two or more distinct semantic interpretations that cannot be reduced to a single core sense. The concept highlights the coexistence of divergent readings within a single word or utterance, rather than a single sense shifting over time. Meaningsplits can arise from lexical polysemy or homonymy, syntactic ambiguity, or the interaction of literal meaning with figurative or contextual readings.

Mechanisms include lexical polysemy and homonymy, where a word has multiple senses (for example bank as financial institution vs riverbank); syntactic ambiguity, where sentence structure allows alternative semantic parses; and pragmatic or metaphorical extension, where context triggers a non-literal sense alongside a literal one. In computational linguistics, meaningsplits can be modeled as competing semantic representations that a disambiguation system must select based on context.

In analysis, researchers may catalog senses, track the historical emergence of splits, and study how discourse and context determine which reading is intended. Meaningsplits help explain why sentences can remain ambiguous in some contexts but become resolved in others, and why words acquire new senses as language evolves.

Related concepts include semantic ambiguity, polysemy, homonymy, metaphor, and pragmatics. The term is not universally standardized; its exact definition varies across subfields, and some writers use it as a general label for any instance of multiple readings associated with a form.
