INTELLIGENCE IS STRENGTH/LIGHT, STUPIDITY IS WEAKNESS/DARKNESS (e.g., 'feeble-mindedness', 'dim-witted').
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- "Imbecile" is used, but the noun "imbecil'nost'" (имбицильность) is a direct borrowing, less common. Avoid over-relying on it. It's much harsher than simple "glupost'" (глупость).
Common Mistakes
- Misspelling as 'imbicility' or 'imbasility'. Confusing it with 'imbecile' (the noun/adjective). Using it in casual contexts where 'stupidity' or 'idiocy' would be more natural.
