  • Avoid direct calque from 'затемнение' for abstract uses; use 'concealment' or 'obfuscation'. For physical darkness, 'затемнение' or 'помутнение' may fit.

Common Mistakes

  • Using 'obscurity' interchangeably (obscurity is a state/quality; obscuration is the process/act).
  • Misspelling as 'obscurration'.
  • Using in casual speech where 'blocking', 'hiding', or 'darkening' would be natural.
