- Beware of the phonetic spelling: 'Маннергейма' is the standard transliteration, not 'Маннерхайм'.
Common Mistakes
- Misspelling: 'Mannerheim' as 'Mannerhiem', 'Manheim', or 'Mannerheim's Line'.
- Using it as a common noun (e.g., 'a mannerheim line') instead of a proper noun (the Mannerheim Line).
- Confusing it with the later 'Salpa Line'.
