The Metonymy is a phenomenon of language with which we can come up when we refer to a metaphor, since it is the renaming of a circumstance or product under time how or why it is used. The term is used to denote within the field of writing the transnomination of things, with a literal purpose. Metonymy is extremely important in the different ranges of literature, since this provides the reader with a clear understanding and adaptable to a diverse and any situation.
Let's see examples and denote how metonymy is more common than it appears to be: When we say: " The boot of the pants " we are referring to the hole where the leg comes out in a garment that covers the lower part of the body, a boot is a type of high and robust footwear, what the hole in the pants and the footwear have in common is the area where the body goes, that is why in community it is easily expressed and is denoted that way, employing a metonymy in a truly gross matter and with no intention of being more than a nickname.
When studying semantics we find endless tools and utilities with which the writer is able to immerse those who read in an endless world of their own imagination, metonymy is one of the most used by writers today, since this utility allows making great comparisons with objects easy to perceive with the senses. When someone " pledges allegiance to the flag " is not referring to the colored cloth box that identifies any organized entity, he is referring to that he is going to give his loyalty to the nation or institution that that flag represents, it is only idea of what you mean, even if it sounds better that way. Metonymy is not an idiom, but it is part of the semantics, an essential factor when developing an idea that is expected to be understood with simple examples or representations that are simpler and less apotheosis to understand.
