Liminal Space The word liminal comes from the Latin word ‘limen’, meaning threshold – any point or place of entering or beginning. A liminal space is the time between the ‘what was’ and the ‘next.’ It is a place of transition, a season of waiting, and not knowing. Liminal space is where all transformation takes place, if we learn to wait and let it form us.
