Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "лациния" (a non-word). It has no common Russian equivalent. In translation, a descriptive phrase like "внутренняя лопасть максиллы" (inner lobe of the maxilla) or "узкая доля" (narrow lobe) is necessary.
Common Mistakes
- Pronouncing it /læˈkɪniə/ (with a hard 'c'). Correct is /ləˈsɪniə/.
- Using it outside of biological contexts.
- Assuming it is a common word.
