What is the end of a toponym is a question that may seem curious only to those who do not have full perception of the continuous recycling place names undergo, passing from one typology (or category) to another in the onymic ambit, or lexicalising themselves. This paper will try to: a) analyse a corpus of toponyms of every kind from a specific space and time ambit, that is a square in the city of Rome, Piazza Bologna, and its surroundings; b) examine the transonymic process such toponyms have undergone; c) verify whether there are recurrent transonymic paths or ones that are more specific for particular typologies of toponyms. The essay opens with an ample terminological introduction and is then articulated in chapters about hodonymic hyperonyms (as underground trains stations), hodonyms deriving from toponyms and transonymies linked to vehicles and various commodities sectors
