Conceptual Metaphor

MAINTENANCE IS PREPARATION (De-icing is a preparatory act for safe operation).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not confuse with 'разморозить' which is more general for 'defrost'. Use 'удалить лёд' or 'обезледенить' (technical) for precision.
  • Avoid literal 'де-айс'.

Common Mistakes

  • Confusing 'de-ice' (remove ice) with 'defrost' (remove frost/thaw). 'Defrost' a freezer; 'de-ice' a windscreen.
  • Incorrect: 'I need to de-ice the frozen chicken.' Correct: 'I need to defrost the frozen chicken.'
