‘Dead name’ refers to the first name(s) that a trans person discarded during their transition. Many trans people do not want to hear or read their dead names. These names can be associated with negative emotions and traumas. Besides, dead names possibly refer to a person that never actually existed. However, not all trans people change their first names.
Deadnaming a trans person without their consent in front of people who did not know their birth name can also be a form of outing (see below).
