Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- False friend with 'эстетика' (aesthetics). 'Anesthetic' is 'анестетик' or 'обезболивающее'. Confusion between 'local anesthetic' (местная анестезия) and 'general anesthetic' (общий наркоз).
Common Mistakes
- Misspelling: 'anasthetic' (incorrect). Confusing 'anesthetic' (substance) with 'anesthesia' (the state). Using as a verb ('They anestheticked me' is wrong; correct: 'They anesthetized me').
