Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'гравий' (gravel) which is a collective term for small stones. 'Pebble' is typically one stone. 'Булыжник' is often a 'cobblestone', which is larger than a pebble.
Common Mistakes
- Using 'pebble' for a sharp, jagged stone (use 'stone' or 'shard'). Using 'pebble' as a mass noun (*'The path is made of pebble') instead of 'pebbles'.
