Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid using 'декодировать' for simple 'understanding'. In Russian, 'расшифровать' is a closer match for both literal and metaphorical uses of 'decode'.
- Do not confuse with 'decrypt' which is more specifically about breaking encryption; 'decode' can be for non-secret codes (e.g., barcodes).
Common Mistakes
- Incorrect: 'I decoded to read the message.' Correct: 'I decoded the message.' (requires a direct object)
- Incorrect preposition: 'decode in plain text'. Correct: 'decode into plain text'.
