Etymology

The word "unsettling" combines the prefix "un-" (Old English "un-," meaning "not") with the verb "settle" (from Old English "setlan," meaning "to place firmly or make calm"). The suffix "-ing" forms the present participle or adjective. Originally, "settle" implied physical stability (e.g., settling land), but by the 16th century, it gained psychological connotations (e.g., calming emotions). Adding "un-" reverses this, creating a sense of disruption or unease.
