Common Pitfalls
Translation Traps (for Russian speakers)
- False friend: Do not translate as 'сердечная скорлупа' which is nonsensical. The correct equivalent is 'сердцевидная раковина' (heart-shaped shell).
- Avoid conflating with 'перламутр' (mother of pearl), which is a material, not a shape.
Common Mistakes
- Using 'heart shell' to refer to any pretty shell (it is a specific type).
- Misspelling as 'heartshell' (should be two words).
- Overusing the poetic metaphor, making prose sound forced.
