May Day, Mayday and SOS

Vulcan and Maia (1585) by Bartholomäus Spranger

First off, the month of May was named for the Greek goddess Maia, who was identified with the earlier Roman goddess of fertility, Bona Dea, whose festival was held in May.

The holiday called May Day falls on the first day of May and it is a chance to celebrate spring moving into summer. Included in the outdoor celebrations is dancing around a maypole. In Wales, this festival was connected to the May Queen (Creiddylad) and the maypole and its dance is a remnant of the old festivities.

May Day is an ancient northern hemisphere spring festival and today is a national holiday in more than 80 countries and celebrated less officially in other countries.

But May Day is not to be confused with the distress call mayday which is used primarily by aviators and mariners, but in some countries local organizations such as firefighters, police forces, and transportation organizations also use the term. This term came into English in the early 1900s. It derives from the French venez m'aider, meaning "come help me".

The call is always given three times in a row ("Mayday Mayday Mayday") to distinguish an actual Mayday call from a message about a Mayday call. (Making a false distress call in the United States is a federal crime.)

The Mayday call sign originated in 1923 with Frederick Stanley Mockford who was a radio officer at Croydon Airport in London. He thought, especially because much of the traffic at the time was between Croydon and Le Bourget Airport in Paris, that "mayday" from the French would be understood by both sides since it was taken from the French m'aider ('help me'), a shortened form of venez m'aider ('come and help me').

While ships can also  issue a mayday radio call, originally the Morse code "SOS" was the more common distress signal. "SOS" does not mean Save Our Souls or Save Our Ship as I was once told. It was adopted in 1905 by German ships for signifying distress. The British working with Marconi radio operators wanted to keep CQD (General Call Disaster though sometimes translated as Come Quick Disaster) as a distress signal.

It was first suggested to use SOE, but the small "E" dot in Morse code can easily be lost. The suggestion was then to use SOS, which was adopted at the Berlin Radiotelegraphic Convention in 1906 as the official international standard for distress calls. The first time the SOS signal was used in an emergency was on June 10, 1909 when the Cunard liner "SS Slavonia" wrecked off the Azores.

Prius (automobile)

2019 Toyota Prius 

The Toyota Prius is a full hybrid electric automobile developed by Toyota and manufactured by the company since 1997.

When Toyota was namining the world's first mass-produced hybrid vehicle, they wanted a name that would connect to it being groundbreaking and the predecessor of the cars of the future. They turned to latin and chose "prius," meaning "first," "original," or "to go before."  It is the root of our modern word "prior."

An odd controversy surrounding the name emerged when people wanted to refer to more than one of the cars. What is the correct plural form?

The two leading contenders were "Prii" and "Priuses." Toyota initially said the plural was "Prius" (like moose or deer). But in February 2011, Toyota USA asked the US public to decide on what the most proper plural form of Prius should be. The choices included Prien, Prii, Prium, Prius, or Priuses. "Prii" was the most popular choice, but it was close - “Prii” received 25% but “Prius” came in a close second with 24%.

Technically, in Latin, the plural of “Prius” is actually “Priora” or “Priores.” (Latin assigns gender to nouns. “Priores” is the feminine plural, while “Priora” would be the neuter plural form.) Priora is a brand name used for a Russian automobile, the Lada Priora in 2007.

And don't be surprised if you still hear people use "Priuses" as the plural in English.

Wikipedia

Wikipedia has become the place to go online to start your search for information about - well, just about anything. With its launch in 2001 as an online, editable English-language encyclopedia, it quickly captured a user base and thousands of editors who monitor the articles.

Versions in other languages were quickly developed, but the with more than 6 million articles, the English Wikipedia is the largest of the more than 290 Wikipedia encyclopedias. The numbers keep growing, but Wikipedia comprises more than 40 million articles in 301 different languages. It is one of the top 5 websites visited in the world.

Wikipedia was launched on January 15, 2001, by Jimmy Wales and Larry Sanger. Sanger was the one who coined its name. It is a portmanteau of "wiki" and "pedia" from encyclopedia. But what are the origins of those two words? 

According to Wikipedia:

"The word encyclopedia comes from the Koine Greek ἐγκύκλιος παιδεία,^[8] transliterated enkyklios paideia, meaning "general education" from enkyklios (ἐγκύκλιος), meaning "circular, recurrent, required regularly, general"^[9] and paideia (παιδεία), meaning "education, rearing of a child"; together, the phrase literally translates as "complete instruction" or "complete knowledge".^[10]However, the two separate words were reduced to a single word due to a scribal error^[11] by copyists of a Latin manuscript edition of Quintillian in 1470.^[12] The copyists took this phrase to be a single Greek word, enkyklopaidia, with the same meaning, and this spurious Greek word became the New Latin word "encyclopaedia", which in turn came into English."

The -pedia part is pretty obvious, but wiki is less obvious. Wikis existed before Wikipedia and the word is still used to describe websites with content that is specifically designed to be edited by its users. "Wiki" was first used by Ward Cunningham to describe software he wrote in 1994 that was meant to speed up the communication process between computer programmers.

Cunningham borrowed the word from the Hawaiian language, where it means "fast," after he heard it in the Honolulu airport when an employee told him to take the "Wiki Wiki Shuttle" between terminals.

An erroneous etymology is that wiki is an acronym for "What I Know Is." Some people applied that definition to the word later, making it a backronym.
