| Name order reversed | Hungarian writes the family name before the given name: Nagy Péter is Mr Nagy. Copy the order literally into a German form and the given and family names are swapped. | We transpose to the given-name-first order and match the result to the passport, so the registry office reads it correctly. |
| Agglutinative case endings | Hungarian has no prepositions; it stacks case suffixes (-ban, -ból, -val) onto the noun. Rebuild them as separate German words wrongly and the meaning bends. | We render the case relations correctly, mapping suffixes to the right German prepositions and structures. |
| Vowel harmony | Each suffix has two or three variants chosen by the vowels of the stem (-ban vs -ben). The wrong variant is an immediate marker of a non-native text. | Suffixes are formed by vowel harmony, so the Hungarian reads as native, not assembled. |
| Definite vs indefinite conjugation | The verb changes according to whether its object is definite: olvasok (I read something) vs olvasom (I read it). Choose wrong and the reference is lost. | The definite or indefinite form is set deliberately, so what is being referred to stays clear. |
| No grammatical gender | Hungarian has one pronoun, ő, for he and she. Translating into German or English, the gender has to be recovered from context, not guessed. | Gender is resolved from the document and the parties, not assumed — so titles and pronouns are right. |
| Long diacritics carry meaning | Vowel length is distinctive and marked by accents; the double-acute ő, ű are often dropped by foreign systems, changing a name or a word. | Long vowels and the double-acute letters are preserved and matched to the ID, so names are not silently altered. |
| The formal register | Hungarian marks courtesy through Ön, maga and verb forms. The wrong choice makes an official letter too familiar or oddly distant. | The courtesy register is set for the document type — formal where an authority expects it. |
