Other forms: liminalities
Liminality is a quality of being in between two places or stages, on the verge of transitioning to something new. There's a liminality to the brief moment between being asleep and being fully awake.
Periods of liminality are transitional, sometimes disorienting, and frequently involve waiting for something new to begin. A good example is the summer after high school graduation; whether you're starting college in the fall or looking for a job, you're on the verge of crossing a threshold into a new stage of your life. Liminality is rooted in this idea of a threshold (limen in Latin), a kind of doorway between the past and the future.
