Questions about where Basque came from I have read that Basque is one of the so-called language isolates. I see that you live in Spain. Yet actually a conscientious linguist can give no simple answer. My own opinion is that really learning any language is hard work.
Some people nevertheless enjoy the adventure.
That again depends on which other languages you're comparing with, and what you know before you learn them. This is because European languages are pretty similar to each other, in global terms, and also because they have a great many words, phrases, and even grammatical devices in common. Basque is an exception in this sense, at least to some extent. The reason is that it is not related to all those other European languages, which unlike Basque belong to a single language family called Indo-European. Basque is different, and different is usually harder to learn.
