Sanskrit is very consistent in its rules too.

We had it in school in grades 8-10 or so and I really enjoyed learning it. The grammar rules are fairly simple and there are not many of them, IIRC. Words can be made up out of smaller words by joining them together by simple rules.

Another interesting thing is that many words have multiple meanings, a fact that poet and prose writes in the Sanskrit literature leveraged heavily. So a passage of text can have multiple layers of meaning.

It is almost like a programming language where you compose bigger structures such as functions and classes out of the atomic elements of the language.
