* Scottish Gaelic: As they ruled Scotland, the Stuarts would have been familiar with Scottish Gaelic, the language of the Highland clans. This exposure would have varied between monarchs, with some having more connections to the Highlands than others.
* French: The Stuarts had strong ties to France, with many members of the family spending time there. This likely meant they were fluent or at least proficient in French.
* Latin: Latin was the language of scholarship and diplomacy in the 17th and 18th centuries, so the Stuarts would have had some level of Latin education.
* Other languages: Depending on their specific travels and connections, individual Stuarts might have learned other languages, such as Spanish or Italian.
It's important to remember that language use in the past was very different from today. While we might think of languages as fixed, individuals in that era might have spoken different languages depending on their social context, who they were speaking to, and where they were.
