RésuméIn the Roman universe of Réjean Ducharme, the names create networks of meanings that spread throughout the text. Ducharme’s onomastic creation, as well as the theoretical rhetoric he speaks about names, is a real constellation of analogy, opposition or equivalence, both between the names themselves and with respect to the characters they designate. At the extreme of the Ducbarmian nomination, the name is part of a realistic philosophy — the name designates the thing. At the other extreme, he is involved in an aggravating nominalism — it is just a name. There is a constant between these two poles: the desire to join the other, to take ownership of it, to merge with him. The name inevitably raises the question of the alteration or, more precisely, the refusal of the alteration.
