The origin of the ampersand was always one of the first things Langdon taught his symbology classes. The symbol “&” was a logogram—literally a picture representing a word. While many people assumed the symbol derived from the English word “and,” it actually derived from the Latin word et. The ampersand’s unusual design “&” was a typographical fusion of the letters E and T—the ligature still visible today in computer fonts like Trebuchet, whose ampersand “” clearly echoed its Latin origin.
