Common Pitfalls
Translation Traps (for Russian speakers)
- Might confuse with 'выступать' which has broader meanings including 'to perform' or 'to advocate'; ensure context specifies physical sticking out.
- Avoid direct translation where 'protrude' implies unintentional extension, unlike more active verbs.
Common Mistakes
- Using 'protrude' transitively (e.g., 'He protruded his tongue' is incorrect; use 'His tongue protruded').
- Confusing 'protrude' with 'extrude', which involves forcing material out.
