Etymology
the word "salvo" entered english in the late 16th century from italian, where "salva" denotes a salute or discharge of firearms. the italian term itself originates from the latin "salve!", the imperative form of "salvere" meaning "to be in good health," used as a greeting. the conceptual shift from a greeting of health to a simultaneous discharge of weapons is attributed to the practice of firing guns as a ceremonial salute or honor. thus, the modern meanings of a military volley or a sudden outburst evolved from this ceremonial act of respect.
