Differences
Term is equally rare in both varieties. The metaphorical use might be slightly more attested in British literary sources due to the presence of such stones in the UK landscape (e.g., Cornwall, Yorkshire).

Frequency
Extremely low frequency in everyday language. Higher likelihood of encounter in regional geology, archaeology, or heritage texts, particularly in the UK.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation as 'качающийся камень' unless in a very specific geological context. It is not a generic term for any moving stone.
- Do not confuse with 'краеугольный камень' (cornerstone), which has the opposite meaning of being fundamental and stable.
Common Mistakes
- Using it as a verb phrase ('The stone was rocking') instead of the compound noun 'rocking stone'.
- Confusing it with 'rolling stone', which is a common idiom for a wanderer.
- Capitalising it as a proper name unless referring to a specific landmark (e.g., the Rocking Stone on Troy Hill).
