What is the Full Form of SOS?

2 minute read

First recorded in 1905-10; from the Morse code alphabet, in which three dots (or short clicks) represent the letter S and three dashes (or long clicks) represent the letter O. The letters represented by the radiotelegraphic signal (· · · – – – · · ·) used as an internationally recognised call for help, particularly by ships in distress. The full form of SOS is Save Our Souls. It is also known as Save Our Ship. It is a Morse code that is used as a distress signal to indicate danger. The code indicates that a person is in danger and needs immediate assistance.

SOS remains a common distress signal that can be used with any signalling system. It has been used as a visual distress signal, consisting of three short/three long/three short flashes of light from a survival mirror, for example. Individual letters “S O S” have been spelt out in various circumstances, for example, imprinted in a snowbank or constructed out of logs on a beach. The fact that “S O S” may be read upside down as well as right side up helps with visual identification.
