Gaelic!

If you are Scottish, you can learn Scots Gaelic to reconnect with your roots. Although everyone in Scotland speaks English (or at least Scots English which is a slightly different beast), many people also speak Scots Gaelic. People of Scottish ancestry throughout Canada, the US, Australia, New Zealand, England and throughout the world maintain interest in the language as well.
Scots Gaelic is a celtic language, closely related to Irish Gaelic and Manx, and a little less closely related to Welsh, Cornish and Breton. Like its cousin Celtic languages, there are few published resources to learn Scots Gaelic, but there are a decent number of online sources to learn from, and there are plenty of resources to use to maintain your knowledge of Scots Gaelic, once you've learned a bit.

"An art whose medium is language will always show a high degree of critical creativeness, for speech is itself a critique of life: it names, it characterizes, it passes judgment, in that it creates."
- Thomas Mann
