Hillock is a noun
According to the Merriam Webster dictionary hillock is a small hill or mound.
The word is used in chapter 10 of my reading, the narrator in reference to Paul D and his journeys stated, “when he was lost, and found himself without a petal to guide him, he paused, climbed a tree on a hillock and scanned the horizon…”
Paul D in his quest for freedom was trying to travel north during spring time. Â He was told to follow the trees and flowers. Â When he got lost he climbed to higher ground to see which direction had trees and flowers.
