- Not to be confused with 'морское письмо' as a direct, meaningless calque. The historical Russian equivalent might be 'каперское свидетельство' or 'охранное письмо', but context is crucial.
Common Mistakes
- Using it to refer to modern ship documents (like a Certificate of Registry).
- Confusing it with a 'letter of marque' (which authorizes privateering).
- Spelling as 'sealetter' or 'sea-letter' without the space (the standard historical form uses a space).
