This study reviews what kind of neologisms have appeared between the period of 2003-2004, categorizes them, and examines how they have been interpreted in order to faithfully convey what the speaker's intent is, that is the vouloir-dire. The presentation covers the following points: 1) reasons for the formation of neologisms; their impact on TL expression and how it is managed in SL, 2) review correspondence and/or equivalence strategies by neologism category. The latter part discusses how the widespread use of neologisms should be reflected in the pedagogy of interpreters in order to ensure that they do not interpret the literal meaning but rather are faithful to the speaker's meaning, in order to ensure intelligibility, thereby remaining competitive in this ever-changing interpretation market through clear and effective communication.
