# `translation.placeholder_unknown`

A wording writes a field the message does not have.

Area 10, [Configuration and time](../topics/configuration-and-time.md); not declinable; the next step is usually the agent's.

A wording writes only the fields its message has.




```jadpo
translations {
    order_shipped: "La commande de {nom} a été expédiée."
}
```

```text
error: `{nom}` isn't a field of `OrderShipped`
 --> domains/shipping/translations/fr_fr.jadpo:2:36
  |
2 |     order_shipped: "La commande de {nom} a été expédiée."
  |                                    ^^^^^ no such field
  reason: `OrderShipped` has no field `nom` a wording can write; this wording may write `{name}`.
  next: Remove `{nom}`, or add the field to `OrderShipped` (agent)
