ambiguity

Ambiguity is the quality of being open to more than one interpretation. In language and communication, it arises when a word, phrase, sentence, or symbol can be understood in multiple ways. It can result from polysemy (one word with several related meanings), homonymy (distinct words sharing a form), syntactic structure, or insufficient context.

Common forms include lexical ambiguity, where a word has several meanings; syntactic ambiguity, where a sentence’s structure allows more than one parse; semantic ambiguity, where the meanings of words combine in unclear ways; referential ambiguity, when it is unclear which entity a pronoun or demonstrative refers to; and pragmatic ambiguity, where the intended force or implication depends on context.

Examples illustrate the phenomenon. The bank can refer to a financial institution or a riverbank. I saw the man with the telescope is ambiguous about who possesses the telescope. The sentence “Visiting relatives can be a nuisance” can mean relatives who visit or the act of visiting relatives. Visual ambiguity also occurs in images, such as the Rubin vase, which can be seen as either a vase or two faces.

Ambiguity has both drawbacks and uses. In everyday communication it can cause misinterpretation or disputes, as in law or contracts. It poses a challenge for automated systems, which rely on context and world knowledge to disambiguate. In literature and rhetoric, intentional ambiguity invites multiple interpretations and depth, contributing to nuance and ongoing interpretation.
