Common Pitfalls
Translation Traps (for Russian speakers)
- Not a 'куст' (bush) which is a single plant; a clump is multiple items. Not a 'комок' (lump) which is usually a single, often round mass; a clump is a group. The verb 'to clump' differs from 'топать' (to stomp) which is more intentional.
Common Mistakes
- Using 'clump' for a neatly arranged bouquet (use 'bunch'). Confusing 'clump' (group) with 'lump' (single solid mass).
