Imagine a medieval knight's LANCE made of IRON (French 'fer')—this snake's head is lance-shaped and its bite is as piercing as steel.
Conceptual Metaphor

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate literally as 'железное копье'. It is a fixed zoological term 'фер-де-ланс' or, descriptively, 'копьеголовая змея' or 'ланцетоголовая змея'.
Common Mistakes
- Using it as a general term for any snake.
- Misspelling as 'fear-de-lance', 'far-de-lance', or 'fer de lance' (often without hyphens).
- Incorrect plural: 'fer-de-lances' is acceptable, but 'fers-de-lance' follows French pluralization (though rare in English).

FAQ
Frequently Asked Questions
No, it refers specifically to neotropical pit vipers of the genus Bothrops, primarily Bothrops asper.
It is highly unlikely and would sound very technical. You would typically say 'a venomous snake' unless in a specific context.
The name originates from French, meaning 'spearhead' or 'lance head', describing the shape of the snake's head. It came into English via zoological classification.
Give it a wide berth and do not attempt to handle or provoke it. Its strike can be fast and its venom is medically significant.
