Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'achieve' (достигать).
- Avoid direct translation as 'Ахилл' (the name Achilles); the Russian equivalent is 'ахиллесова пята'. The English 'achill' is an adjective/noun derived from it.
- The stress is on the second syllable (a-KILL), not the first.
Common Mistakes
- Spelling: 'achile', 'achille'.
- Pronunciation: /ˈætʃɪl/ (like 'atch-ill'). Correct is /əˈkɪl/.
- Using it as a verb (*to achill something).
- Overusing it in low-register contexts where 'big weakness' would suffice.
