betweenhood

The state or condition of being between or in-between; intermediate condition; betweenness.

Mörike, writes one scholar, is situated historically in a state of Zwischenheit, or “betweenhood”; [...]

That which is between or in-between; anything intermediate.

This fence, this gap, this indeterminate betweenhood, is the discursive condition of semiotics, as the semiotic is the condition of all conversation.
