Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid translating as 'верный друг' (faithful friend) without the specific literary/connotative weight. It is more specific than a general good friend.
  • Do not confuse with 'соратник' (comrade-in-arms) which implies shared struggle more than personal devotion.
  • It is not a simple 'помощник' (assistant).

Common Mistakes

  • Incorrect spelling: 'fidas achates', 'fidus achates'.
  • Mispronunciation of 'achates' with a hard 'ch' (/tʃ/) instead of a 'k' sound.
  • Using it to describe a romantic partner.
  • Treating it as two separate words grammatically (e.g., 'He is very fidus').
