No, it means the basic parts of the language.

It is an English term that means the basic parts of a larger whole (comes from building - where they are made from bricks/blocks).

See the Chambers dictionary, in particular 3 (highlighted):

building block noun 1 a hollow or solid block, larger than a brick, made of concrete or other material. 2 a child's toy, usually a cube made of wood. 3 any of the separate parts out of which something is built.
