Most acronyms are acronyms, that is, a word formed by the initials of a term. But that’s not the case with SOS, which was invented as a distress signal in Morse code. The sequence of digits “• • • – – – • • •” was chosen, in the last century, for its ease and neutrality. The three dots correspond to “S” and the three spaces to “O”. Later, the acronym began to be associated with terms such as “Save our souls” (“Save our soul”), “Save our seamen” (“Save our sailors”) and “Save our ship” (“Save our ship”) , among others. All emerged in popular culture as a way to associate SOS with your sense of safety, rescue or rescue, but none of them are officially valid.
