Having been interrupted, upset, or moved from a settled state; emotionally or mentally unbalanced.
From Latin disturbare, combining dis- (apart) and turbare (to disorder, confuse). Originally meant 'to throw into disorder' and evolved to encompass both physical disruption and psychological distress by the 14th century.
The word 'disturbed' captures both external chaos and internal turmoil because the Latin root 'turbare' is related to 'turbulent' - whether we're talking about disturbed sleep or a disturbed mind, the metaphor is of peaceful waters being churned into chaos.
