[Middle English, from Old French alarme, from Old Italian allarme, from all'arme, to arms : alla, to the (from Latin ad illa : ad, to; see ad- + illa, neuter pl. of ille, that, the; see al-1 in Indo-European roots) + arme, arms (from Latin arma; see ar- in Indo-European roots).]
c.1325, from O.Fr. alarme, from It. all'arme "to arms!" (lit. "to the arms"). An interj. that came to be used as the name of the call or warning. Extended 16c. to "any sound to warn of danger or to arouse." Weakened sense of "apprehension, unease" is from 1833. Variant alarum is due to the rolling -r- in the vocalized form. The verb is 1590, from the noun. Alarmist "one addicted to sounding alarms" is from 1793.
