Polysemy (/pəˈlɪsᵻmi/ or /ˈpɒlᵻsiːmi/; from Greek: πολυ-, poly-, "many" and σῆμα, sêma, "sign") is the capacity for a sign (such as a word, phrase, or symbol) to have multiple meanings (that is, multiple semes or sememes and thus multiple senses), usually related by contiguity of meaning within a semantic field.
