By way of example, the common ampersand (“&”) represents theLatin conjunctive word et, for which the English equivalent is the word “and”. The ampersand’s symbol is a ligature, joining the old handwritten Latin letters e and t of the word et, so that the word is represented as a single glyph.[1]” wikipedia
