alarmed
UK: əˈlɑːmd | US: əˈlɑːrmd
adj. feeling fear or anxiety caused by sudden danger or threat
adj. equipped with an alarm system
The word "alarm" originates from the Old Italian phrase all'arme! ("to arms!"), a call to action in military contexts. It combines a- (to) + arme (arms/weapons), later adopted into Middle French as alarme. The suffix -ed transforms the noun into an adjective, describing a state of being warned or frightened. Over time, "alarmed" expanded from literal military alerts to metaphorical emotional responses (fear) and modern technical uses (alarm systems).
