Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid literal translation ('воля-огонька') – it's meaningless.
- Do not confuse with 'ведьма' (witch) or 'привидение' (ghost). The core is elusiveness, not just supernatural.
- Use 'блуждающие огни' for the literal phenomenon and 'мираж', 'призрачная цель' for the figurative.
Common Mistakes
- Spelling: will-o-the-wisp (missing apostrophes), will o' the wisp.
- Using as a concrete noun for a person without the figurative sense.
- Confusing with 'willpower' or the modal verb 'will'.
