Metonymy. Definition: Metonymy in literature refers to the practice of not using the formal word for an object or subject and instead referring to it by using another word that is intricately linked to the formal name or word. It is the practice of substituting the main word with a word that is closely linked to it.
Thesaurus gives analogue as the definition for synonym and equivalent and metonym as synonyms. Poecilonym is the use of different words to refer to the same thing, in literary texts usually known as 'elegant variation'.
