Today's word comes via Italian "salva" from Latin salve "Hail!" the imperative of salvere "to be in good health" from salvus "well, unharmed." This Latin word may be found in numerous English words borrowed from Latin: "salvation," "salvage," and "save" (but not "salve"). The original Proto-Indo-European root was *sol- "whole," which, with other suffixes, also gave us "salute, "solid" and "soldier" by way of French. In Greek that initial [s] became the [h] in holos "whole," found in "holistic" and "holography."
