Common Pitfalls
Translation Traps (for Russian speakers)
- A direct translation trap. The Russian term 'олигофрения' (oligofreniya) is a standard current medical diagnosis. Its English equivalent 'oligophrenia' is obsolete and offensive. Use 'intellectual disability' or 'developmental disability' instead.
Common Mistakes
- Using it as a current, acceptable term in professional English writing.
- Pronouncing it as /ɒlɪˈɡɒfrɛniə/ (misplacing the stress).
- Confusing it with 'dementia' (which is acquired cognitive decline).
