👉 Polysemia is a concept in linguistics that refers to the ability of a word or phrase to express multiple meanings, including synonyms and antonyms. It is characterized by its ambiguity, which means it can be understood in more than one way, depending on the context in which it is used. Polysemia is often used in fields such as philosophy, psychology, and linguistics to explore the ways in which language is constructed and how meanings are conveyed through words.
