The first part of this essay on vocabulary considers some conceptual matters: study of notion, coinage, future and acceptance of neologisms. The second part presents two dozen of recent creations which have attained a certain degree of usage and recognition. They are words according to lexicology (nordique/northern), terms in language of speciality (glace de lumière/ice skylight) or proper names (Radissonie/Radissonia). Geographical and linguistic approaches are used.
