Arnold van Gennep and Victor Turnerm developed the term liminality to “refer to in-between situations and conditions that are characterized by the dislocation of established structures, the reversal of hierarchies, and uncertainty regarding the continuity of tradition and future outcomes”. (Wikipedia)
Meanwhile, in colloquial speech, "limbo is any status where a person or project is held up, and nothing can be done until another action happens". The traditional meaning of limbo has a theological context similar to purgatory, or the place between heaven and hell. (Wikipedia)
Theology aside, I was recently discussing liminality and limbo with my friend Amy who is focussing a Masters in Fine Arts around them.
