Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'лунатик' (sleepwalker/lunatic). 'Lunate' relates only to shape. The Russian adjective 'полулунный' (semilunar) is the closest equivalent.
Common Mistakes
- Using it as a general synonym for 'round' or 'circular'. It specifically means crescent-shaped.
- Mispronouncing it as /lʌˈneɪt/ (lu-NAYT); correct stress is on the first syllable (LOO-nayt).
