Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid directly translating as 'идиотизм' (which is closer to 'idiotism' and less common). The more natural equivalent is often 'глупость', 'безумие', or 'дурость' depending on context.
  • Do not confuse with 'idiomaticity' (идиоматичность).

Common Mistakes

  • Incorrect plural: 'idiocies' is correct but rare. Misspelling: 'idiosy', 'ideocy'.
  • Confusing with 'irony' or 'ignorance'.
