Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not translate as "крысиная охрана" (rat security) or "сторож крысы" (rat watchman). It is a device, not a person or animal. The correct conceptual equivalent is "крысоловный щит" or "защитный диск от крыс".

Common Mistakes

  • Using 'rat guard' to refer to a person who guards against rats.
  • Using 'rat trap' synonymously (a trap catches, a guard blocks).
  • Misspelling as 'ratgard' or 'rat-guard' (standard is space or hyphenated).
