Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'дуодецима' (duodecima) in music, which refers to an interval of a twelfth.
- Do not translate literally as 'двенадцатый' (twelfth); it's a specific book size, not an ordinal number.
Common Mistakes
- Mispronunciation: /duːoʊˈdesɪmoʊ/ is common; the 'c' is soft (/s/).
- Using it as a general adjective for 'small' outside of bibliographic contexts.
- Confusing it with 'octavo' (8vo) or 'sextodecimo' (16mo).
