MORE ABOUT SOS
What does SOS mean?
Morse code uses clicks and pauses, short and long sounds, or flashes of light to represent letters and numbers. S is represented by three short clicks or brief flashes of light, and O is represented by three long sounds or longer flashes of light (depicted with dashes).
Morse code can be written out using dots to represent short clicks and dashes to represent long ones, resulting in a specific sequence for SOS (··· – – – ···) that was chosen since it would be easy to communicate with sounds over radio or with flashes of light.
The signal became well-known enough that SOS came to be used as an informal term for any call for help or notification that there is an emergency, as in Send an SOS to the board letting them know that we’ll have to schedule an emergency meeting.
When used this way, each letter is still pronounced individually (S-O-S). The plural of SOS can be written as SOSs or SOS’s. SOS can also be used as a verb meaning to send such an SOS.
Example: I have my phone set up to automatically send an SOS to certain contacts if I ever dial 9-1-1.
Where does SOS come from?
SOS was officially designated as a distress call in the early 1900s. Contrary to popular belief, the sequence SOS was not meant to stand for “save our ship” or “save our souls,” both of which were applied to the series of letters later. In fact, the letters were not intended to stand for anything—they were chosen simply because they are easy to communicate in Morse code and the resulting sequence is easy to distinguish from any other message.
Morse code has since largely fallen out of practical use in favor of systems based on more advanced technologies, especially satellite communication. However, use of the term SOS as an informal way of referring to a distress call is still common.

How is SOS used in real life?
The signal SOS was once commonly used in the context of radio communication among ships. Today, the use of SOS as a general way to refer to a call for help is informal. It’s sometimes used in situations that aren’t quite emergencies—you might text an SOS to your roommate to bring home ice cream, for example.
At 12.57am, the first use of 'SOS' by the Titanic is recorded. According to Harold Bride, he had asked Phillips what he was sending and was told 'CQD.' Appealing to his sense of humour, Bride suggested using the new call, 'SOS', as it may be his last chance to send it. pic.twitter.com/4qvtqbQMep
