SOS

es-oh-ES
SOS does not stand for Save Our Souls or Save Our Ship. It stands for nothing. It was chosen because three dots, three dashes, three dots is almost impossible to mistake for anything else.
Documented

Documented

The German government proposed the sequence in 1905 and the 1906 Berlin convention adopted it internationally, effective 1908, on grounds of unmistakability, not meaning. The Titanic's 1912 operators famously sent both CQD and SOS. Save Our Souls and Save Our Ship are later expansions with no basis in the convention record.

Assessment: Documented in the ITU convention records and the Titanic inquiry transcripts; the backronyms are universally flagged as folk inventions.
Stories

Stories

The soul-saving versions spread through newspapers within years of adoption, because a meaningless distress call offended the human need for one. CQD, the earlier signal, had already been folk-expanded as Come Quick, Danger, establishing the habit SOS inherited.

Assessment: Documented as contemporary press folklore; false as origin.
Interesting claims

Interesting claims

Signal-design people cite SOS as proof that redundancy beats meaning: the pattern survives noise because it is a shape, not a message. Modern emergency UX, from 911 to the crash-test beep, follows the same law the convention discovered by accident.

Assessment: A genuine design principle, here attached to a genuine historical accident.

Worth asking

The most urgent word ever sent means nothing, and that is exactly why it works. What else in life survives by being impossible to misread?
