Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation "шар огня". The correct equivalent is "энерджайзер", "живчик", or "пробивной человек". "Огненный шар" is only for the literal/physical object.
Common Mistakes
- Using it as a plural (*balls of fire). Using it for objects instead of people (*That car is a ball of fire). Confusing it with 'fireball', which is more common for literal meteors or explosions.
