Polysemy means lexical ambiguity, i.e., the ambiguity of an individual word or phrase that can be used―in different contexts―to express two or more different meanings.
"Polysemes share an etymology, unlike homonyms, which have developed from different sources and coincidently settled upon the same form." (Wikipedia, 2005).
