Limbo comes from the latin limbus meaning a hem or an edge or a boundary. While "limbo" is often popularly understood to be a "place where souls go", the term also describes and reflects theological uncertainty. As such, limbo is not part of the Church's official doctrine (compare purgatory, which is). Official Church teaching remains that the status of these souls (who don't seem to deserve hell, yet cannot follow the divinely-revealed path to heaven) is in limbo – in other words, their fate cannot be determined by any but God.
