Is Scottish Gaelic derived from Irish Gaelic?

No, Scottish Gaelic and Irish Gaelic are sister languages, both descended from Old Irish, a common ancestor. They are not directly derived from one another.

Here's a simplified analogy: Think of them like siblings who share the same parents (Old Irish) but have developed their own unique personalities (differences in vocabulary, grammar, pronunciation) over time.

While they are closely related and share many similarities, there are also distinct differences between the two languages.
