Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'протокол' as a mere 'minutes' or 'record' of a meeting. The English word is broader, focusing on the rules themselves, not just the document. The computing meaning is identical.
Common Mistakes
- Using 'protocol' to mean just 'agreement' without the procedural/rules aspect (e.g., 'We made a protocol' – incorrect). Overusing in informal contexts where 'rule' or 'way' would suffice.
