Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'реф.' (which is not a standard abbreviation). The concept of a precise, numbered reference is key. 'Ref.' is not equivalent to 'ссылка' in all contexts; it is more specific.
Common Mistakes
- Using 'ref.' in spoken language instead of saying 'reference'.
- Confusing 'ref.' (reference) with 'ref' (referee) in sports contexts.
- Incorrect punctuation, e.g., 'ref:' instead of 'ref.'.
