- Avoid a direct word-for-word translation like 'огонь святого Эльма' without the possessive 's' which is crucial for the correct name.
- Do not confuse with 'блуждающие огни' (will-o'-the-wisp), which is a different folkloric phenomenon.
- Ensure the saint's name is 'Elmo' and not a different saint.
Common Mistakes
- Misspelling as 'St. Elmos fire' (missing apostrophe).
- Using it as a countable noun (e.g., 'a Saint Elmo's fire').
- Confusing it with ball lightning or will-o'-the-wisp.
