- Avoid confusing 'lava' with Russian 'лава' (law) which means 'bench' or 'row'.
- Do not translate directly as 'лава' in a geological context; it is always 'лава' in Russian.
Common Mistakes
- Using 'lava' for molten rock still inside the Earth (correct: magma).
- Spelling as 'larva' (an insect stage).
