An archaic or rare term meaning to explain or unfold in detail; to elaborate on something.
From Old French esplait, possibly from Latin ex- 'out' + plait (related to plait, to fold or braid). An obsolete cousin of explain.
Explait is a ghost word haunting medieval English texts—it means the same as explain but sounds more like the act of unfolding something delicate, like carefully unbraiding a complicated knot.
