Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'изгибать' (to bend) in a general sense. 'Incurvate' is more specific, implying a concave or inward curve. The adjective 'incurvate' is close to 'вогнутый'.
Common Mistakes
- Using it intransitively (e.g., 'The road incurvates' is less standard). Confusing it with 'incurve' (a synonym, but less common). Overusing in general contexts where 'curve' suffices.
