Sorry about missing last week, school's been crazy! \ek-SPAY-shee-ayt\ , intransitive verb:
1. To speak or write at length or in considerable detail.
2. To move about freely; to wander.
My writing professor expects me to expatiate my ideas into 6-7 pages, when really, all of my ideas can fit into 3.
Expatiate is from Latin expatiari, "to walk or go far and wide," from ex-, "out" + spatiari, "to walk about," from spatium, "space; an open space, a place for walking in."
