'Polysemy' ( or ) (from the Greek ''πολυσημεία'' = "multiple meaning") is the capacity for a sign (e.g. a word, phrase, etc.) or signs to have multiple meanings (sememes, i.e. a large semantic field). This is a pivotal concept within social sciences, such as media studies and linguistics.

Polysemes

A 'polyseme' is a word or phrase with multiple, related meanings. A word is judged to be polysemous if it has two senses of the word whose meanings are related. Since the vague concept of relatedness is the test for polysemy, judgments of polysemy can be very difficult to make. Because applying pre-existing words to new situations is a natural process of language change, looking at words' etymology is helpful in determining polysemy but not the only solution; as words become lost in etymology, what once was a useful distinction of meaning may no longer be so. Some apparently unrelated words share a common historical origin, however, so etymology is not an infallible test for polysemy, and dictionary writers also often defer to speakers' intuitions to judge polysemy in cases where it contradicts etymology.
There are several tests for polysemy, but one of them is zeugma: if one word seems to exhibit zeugma when applied in different contexts, it is likely that the contexts bring out different polysemes of the same word. If the two senses of the same word do not seem to ''fit,'' yet seem related, then it is likely that they are polysemous. The fact that this test again depends on speakers' judgments about relatedness, however, means that this test for polysemy is not an infallible test for polysemy, but is rather merely a helpful, conceptual aide.
The difference between homonyms and polysemes is subtle. Lexicographers define polysemes within a single dictionary lemma, numbering different meanings, while homonyms are treated in separate lemmata. Semantic shift can separate a polysemous word into separate homonyms. For example, ''check'' as in "bank check"(or ''Cheque'') , ''check'' in chess, and ''check'' meaning "verification" are considered homonyms, while they originated as a single word derived from chess in the 14th century.
For Dick Hebdige^[1] polysemy means that, "each text is seen to generate a potentially infinite range of meanings," making, according to Richard Middleton (musicologist)^[2], "any homology, out of the most heterogeneous materials, possible. The idea of ''signifying practice'' — texts not as communicating or expressing a pre-existing meaning but as 'positioning subjects' within a ''process'' of semiosis — changes the whole basis of creating social meaning".

Examples

★ Mole
# a small burrowing mammal
# consequently, there are several different entities called moles (see the Mole disambiguation page). Although these refer to ''different'' things, their names derive from 1.
e.g. A Mole (espionage) burrows for information hoping to go undetected.

★ Bank
# a financial institution
# a synonym for 'rely upon' (e.g. ''"I'm your friend, you can ''bank'' on me"''). It is different, but ''related,'' as it derives from the theme of security initiated by 1
:'However:' a river ''bank'' is a homonym to 1 and 2, as they do not share etymologies. It is a ''completely different'' meaning. ''River bed'', though, is polysemous with the ''beds'' on which people sleep.

★ Milk

★
★ The verb ''milk'' (e.g. ''"he's milking it for all he can get"'') derives from the process of obtaining milk.

★ Wood
# a piece of a tree
# a geographical area with many trees
