Common Pitfalls
Translation Traps (for Russian speakers)

- Avoid using the Russian word 'вакуум' (vacuum) as a false friend.
Common Mistakes
- Misspelling: *vacilator (missing one 'l'), *vacillater (wrong suffix).
- Incorrect pronunciation: stressing the second syllable (va-CIL-la-tor).
- Using it for a machine or object (it is only for people).
