Translingual[edit]

Etymology[edit]

Chosen because its morse code sequence (· · · — — — · · ·) was easy to remember and recognize even through interference. Many mnemonics and backronyms were later formed from the sequence.

Symbol[edit]

SOS

  1. (radio slang) emergency, mayday, distress

Usage notes[edit]

The code SOS is normally only used in text transmission; for voice communication, mayday is used. The sequence is normally transmitted run together without any letter spacing in between, so it is technically a single unique code rather than a series of three letters.
