upset
UK: ʌpˈsɛt | US: ʌpˈsɛt
vt. to overturn or disturb the normal state of something
adj. distressed or emotionally agitated
n. an unexpected defeat or reversal
The word "upset" originated in the 14th century as a verb combining "up" (indicating direction) and "set" (to place or fix). Originally, it meant "to set up" or "erect," but by the 16th century, it evolved to mean "to overturn" or "disrupt," likely influenced by the idea of lifting something from its stable position. The emotional sense ("distressed") emerged in the 19th century, metaphorically extending from physical disruption to mental agitation.
