Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'пила' (the saw). The word is 'опилки' (pluralia tantum). Translating 'sawdust' as a singular noun can cause errors in sentence structure in Russian.
Common Mistakes
- Using it as a countable noun (e.g., 'three sawdusts'). It is uncountable. Treating it as only from a saw; planers and sanders also produce similar dust.
