Translingual

Pronunciation

• English: (US) IPA^(key): [ɛs.oʊˈʔɛs]

Etymology 1

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

SOS

Usage notes

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.
