| Retroflex vs. dental sounds | Telugu distinguishes retroflex from dental consonants; the difference is meaningful. Levelled, words and names change. | Native phonology is applied, so the right consonant — and the right transliteration — is chosen. |
| Vowel length is meaningful | Short and long vowels form different words. Ignored, a translation renders the wrong word confidently. | Vowel length is read and rendered correctly, so meaning and names are accurate. |
| Andhra vs. Telangana register | Vocabulary and idiom differ between the two states. The wrong register reads as out of place on a document from the other. | The register matching the document's origin is used, Andhra or Telangana. |
| Sandhi at word joins | Telugu fuses sounds at word boundaries (sandhi). Resolved wrongly, words are mis-split and mis-read. | Sandhi is resolved by a native speaker, so word boundaries and meaning are correct. |
| Name order: house name & initials | Telugu names often lead with a house name and initials. Reordered by European habit, the name diverges from the passport. | The name order is handled to match the passport exactly, initials and all. |
| Grammatical gender differs | Telugu's gender system does not map onto German or English. Forced across, agreement goes wrong. | Gender and agreement are handled by Telugu's own rules, not mapped from German. |
| Vowel signs & virama misplaced | Misplaced vowel signs or a stray virama change the syllable — invisible to anyone who does not read the script. | Each syllable is set with its vowel signs and conjuncts correct, so the text renders and reads properly. |
