Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid false cognates like 'каладиум' (which is a direct transliteration and correct but may be unknown). The general term 'декоративное растение с цветными листьями' (decorative plant with colored leaves) may be used descriptively.
Common Mistakes
- Mispronunciation: /ˈkælədiəm/ (incorrect stress). Misspelling: 'caladiam', 'colladium'. Incorrect plural: 'caladiums' is standard, though 'caladia' is sometimes used botanically.
