Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'сиквел' (a film sequel). The Russian medical equivalent is 'последствие', 'осложнение', or 'резидуальное явление'.
- The plural 'sequelae' may be incorrectly perceived as singular due to the '-ae' ending, which is familiar from 'algae', 'larvae'. It is plural.
Common Mistakes
- Using the singular 'sequela' in general text (the plural is standard).
- Misspelling as 'seqeula' or 'sequella'.
- Using it for positive outcomes (e.g., 'The sequela of his training was a promotion' – incorrect).
