Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'взлёт' for aircraft; that's 'takeoff'. 'Liftoff' is specifically for vertical rockets. Figurative use maps to 'старт' or 'запуск'.
- Do not confuse verb 'lift off' with phrasal verb 'lift off' meaning 'remove by lifting'.
Common Mistakes
- Using 'liftoff' for airplane takeoff.* (Technically incorrect, though understood) / *'The airplane had a smooth liftoff.' (Use 'takeoff').
- Misspelling as 'lift-off' in formal technical writing (often solid form is preferred).
