The word 'sos' is commonly understood as a distress signal, often associated with help or an emergency situation. It is an internationally recognized Morse code signal (three dots, three dashes, three dots) used to call for assistance, particularly in situations involving danger at sea or during crises.
The term 'SOS' originated from the International Morse Code signal. It was chosen because of its simplicity and distinct sound, making it easy to recognize. The signal was first adopted by the International Radiotelegraph Convention in 1906 and became widely associated with maritime distress calls.
