What is the difference between a limited partnership and a limited liability partnership?

In a limited partnership, there is at least one general partner whose liability is not limited, and one or more limited partner(s). The limited partners can have both their involvement in the partnership and their liability to the partnership, and externally, limited.

In a limited liability partnership, the liability of the partnership itself is limited, while preserving the partnership entity structure.

There is also a limited liability limited partnership structure, which combines elements of both.
