Sorry for this late blogg about methonymy(
Metonymy is a figure of speech where one word or phrase is used in place of another. The word or phrase used is closely or not so closely associated to the replaced word or phrase.
When a person uses a certain word, which is closely related to what he or she is trying to imply, it is called metonymy. Some examples. When someone says, "Mr. X is addicted to the bottle," what he or she is trying to say is that Mr. X is probably a dipsomaniac, but then substitutes the word 'bottle' for 'alcohol'. The word 'bottle' is a metonymy for the word 'alcohol'. Next example: "He writes with a fine hand" which really means he has nice handwriting.
We know about metaphor, and have practised with examples. Mettaphor really differ from methonymy. The chief difference between Metaphor and Metonymy is that Metaphor is the substituion of a similar word while metonymy is the associationof two contiguous words. Metaphor supresses the ideas while metonymy combines two ideas. In the use of Metaphor, the meaning of an object or a word is transferred to another word or object. But in metonymy there are no such transfer of meaning. Metaphor expresses the similarity between the two words or object while metonymy expresses the association of the words.
For me, this theme seemed confusing but when i search some information i coped with difficulties.
Thanks for attention)
