Deadname

A deadname is the name a trans person was given at birth and no longer uses. The word is deliberately blunt: the name is not old or former, it is dead, and treating it as still current is the thing the term objects to.

It is also a verb. To deadname someone is to call them by it. That can be an accident, and it can be a weapon, and the difference is almost always visible in what happens next.

The accident is ordinary, especially from people who knew someone for years. The repair is short: correct it, move on, and do not make the person manage your embarrassment. An apology that turns into a paragraph about how hard this is for you hands them a second job.

Deliberate deadnaming is something else. Used repeatedly, in front of others, or after a correction, it is a way of saying that the person's own account of themselves does not count. In several jurisdictions it is recognised as harassment in workplaces and schools.

Old documents make it stubborn. Diplomas, medical files, bank records and immigration papers can carry it for years, sometimes permanently, and in many countries changing them is expensive or impossible. Encountering it in a database is not the same as being deadnamed by a person, though it can land nearly as hard.

Some trans people share their deadname freely, some never say it, and the same person may do both depending on who is asking. It is not information anyone else is owed, and asking for it out of curiosity is asking to be trusted with something that has only ever been used against people.

Deadnaming does not require bad intent to do damage

The usual defence is that no harm was meant, which is often true and is not really the question. The effect is the same either way: the person is reminded that an old version of them is still in circulation, and everyone within earshot hears a name they were not given. Intent decides what should happen next, not whether anything happened.

The second confusion is that using a deadname is necessary for clarity, in a story about the past or an introduction to someone who knew them before. It almost never is. People manage to tell those stories with the right name, and the version where the old name appears is usually a version being told for the teller's convenience.
