What is the Meaning & Definition of polysemy

At the behest of the grammar, polysemy is the plurality of meanings that holds a certain word or any other linguistic sign. In addition, the polysemy term is used to designate the plurality of meanings that presents a message beyond the signs be sampled. The origin of polysemy can be due to different reasons... In figurative language it is common that polysemy is generated as result of metaphors and the metonymies, such is the case: in the arms of a spider and the legs of a table; also, technical language or specialization give to some words meaning specific, as is the case with mouse for mouse. Other common reasons of polysemy are also foreign influence in some languages and application changes, for example, the Word button is especially used to refer to those items of clothing that were used to close them or arrest them, however, influences and changes made to also start to call those pieces that bring some electrical appliances button such is the case of radio or television and that enable its operation, or change some of its functions to be oppressed. For example, the Word Bank is a polysemic Word, since it concerns different issues at the same time, on the one hand, is called Bank to that seat of one, two, three or more bodies in which people feel and on the other hand, Bank, also referred to the financial institution that dedicates itself to capture resources, either in the form of deposits or lending money. We found another case of polysemy in the word letter, being able to be on the one hand that writing, usually closed, that is sent to a particular person to communicate particular situation or news. And on the other hand, a letter is one of the cards of a deck of playing cards.
