Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing with 'bump' (шишка) which is more solid. 'Bulge' is more about a stretched, curved surface. Not directly equivalent to 'выпуклость', which is more geometric.
Common Mistakes
- Using 'bulge' for a permanent, solid hill or mound. Confusing verb form: 'The wall was bulging' (correct) vs. 'The wall bulged outwards' (redundant).
