One of the most interesting things about the word "shalom" is its derivation in Hebrew. All Hebrew words can be traced to a 3 letter root. "Shalom" is derived from the root Hebrew letters Shin, Lamed, Mem. This is the same root as the verb: "L'shalem" or "to complete." So the meaning of Shalom as "peace" also has the lovely connotations of "completeness," "wholeness," or "sufficiency."
