- Avoid translating 'Purchase' as "Покупка Луизианы" in overly commercial terms; it is a historical treaty. Prefer "Приобретение Луизианы" or the established historical term "Луизианская покупка".
- Do not confuse with the modern state of Louisiana, which is only a small part of the Purchase territory.
Common Mistakes
- Incorrect: 'the Louisiana purchase' (lowercase 'p').
- Incorrect: 'He Louisiana Purchased the land.' (using as a verb).
- Incorrect: Confusing it with the later 'Gadsden Purchase'.
