Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation with 'смазка' in highly figurative contexts; it may sound overly mechanical. In social contexts, 'социальный катализатор' might be closer than 'социальная смазка'.
Common Mistakes
- Using 'lubricator' (the device) instead of 'lubricant' (the substance). Confusing 'lubricant' (noun) with 'lubricate' (verb).
