Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'de' (a French particle of nobility) as Russian preposition 'de' or 'из'. It remains 'de' in transliteration: 'де Бройль'.
Common Mistakes
- Incorrect capitalization (e.g., 'De Broglie', 'De broglie').
- Pronouncing 'glie' as /ɡlaɪ/ instead of /ɡli/.
- Treating it as a common noun (e.g., 'a de broglie').
