What does unsettle mean?
To unsettle is to disturb something that had seemed calm, settled, or secure. The word can describe a person’s reaction to troubling news, as in a report that “unsettled” the market, or the effect of an event on negotiations, an agreement, or an established system. It may also be used intransitively, though less commonly, to mean that a person or situation becomes uneasy. “Unsettle” is similar in meaning to “disturb,” “upset,” and “destabilize,” but it often carries a sense of doubt or loss of stability rather than outright chaos. The related adjective “unsettled” describes conditions or feelings that are unresolved or insecure, while “unsettling” describes something that causes discomfort or anxiety. The word is useful because it captures the subtle process by which confidence, certainty, or equilibrium is disturbed.
