What does polysemy mean?
Polysemy is the condition in which one word or grammatical unit has several related meanings. It is an ordinary feature of language rather than a defect: words such as “run,” “light,” and “bank” gain meaning from their grammatical roles, contexts, and established usages. In linguistics, polysemy differs from homonymy, which involves distinct words sharing the same form but having unrelated meanings, and from ambiguity, which more generally describes a situation in which an expression can be interpreted in more than one way. The related senses of a polysemous word are normally connected by history, conceptual association, or shared semantic structure. Lexical polysemy concerns multiple meanings attached to a word, while semantic polysemy can describe ambiguity arising within larger expressions or meanings connected through a network of associations. Recognizing polysemy helps readers and speakers see that a word need not have one fixed definition and that a particular context can guide which of its established senses is intended.
nounThe phenomenon by which a single word or other grammatical unit has several related meanings or senses. For example, “bank” can refer to a financial institution, a sloping land beside water, or a set of money kept by a bank.
- The existence of multiple related meanings or senses within a single word, phrase, or other grammatical unit.
"The novel's central character undergoes a profound change, introducing polysemy into the meaning of his once-familiar name."
"The dictionary distinguishes polysemy from a simple lack of contextual clarity."
"Because the senses of “bright” are closely related, its use illustrates lexical polysemy."
The plural is polysemies, with the final “s” following the “e” in “-emy.”
"The study compares different kinds of polysemies across a group of closely related languages."
Words rarely carry just one meaning: polysemy is the linguistic superpower that lets a familiar word keep unfolding.

Where does polysemy come from?
Polysemy combines the combining form poly-, from Greek polýs meaning “many,” with -semy, from Greek sēma meaning “sign” or “meaning.” It entered English in the 19th century as a term for the multiple or varied meaning attached to a word. Its relatives include semantic, sememe, seme, and semiotics, all associated with the Greek vocabulary of signs and meanings.
