Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'проходить' in the sense of 'to pass (an exam)'. 'Undergo' implies enduring, not succeeding.
- Avoid direct translation from constructions with 'подвергаться' if they sound unnatural in English (e.g., 'He underwent criticism' is correct but less common than 'He faced criticism').
- Remember the past participle is 'undergone', not 'undergoed'.
Common Mistakes
- Incorrect tense: 'He has underwent surgery.' (Correct: 'He has undergone surgery.')
- Using it for positive, chosen experiences: 'I underwent a wonderful holiday.' (Incorrect. Use 'I had' or 'I enjoyed').
- Confusing spelling: 'undergoe' or 'undergo' in past forms.
