Rooted in secrecy

Ammon- and krypto-, roots of this month’s words in question, have a common meaning: “hidden”. Despite their mysterious roots, each refers to a well-known chemical substance, the most famous of which is the fictional kryptonite. Originally coined to describe one of Superman’s few weaknesses, kryptonite has become a highly visible word in the English language. In this instalment, we reveal the secrets of its origin, along with the real-life substances ammonia and krypton.

ammonia

Amon or Amun, meaning “hidden” in Ancient Egyptian, was the name of the Theban god of air and invisibility. The cult of Amon became extremely prominent in Ancient Egypt, as Amon came to be identified with the Egyptian creator-sun god Ra. A temple to Amon was built in Siwa, in modern-day western Egypt; Ancient Romans would consult its oracle. When the Romans began extracting ammonium chloride from the ground near the temple they named it sal ammoniacus in honour of Amon. The Latin adjective ammoniacus is a borrowing from the Ancient Greek ammōniakos “relating to Amon”. However, the term ammonia did not appear until 1782 in scientific Latin, and at the turn of the nineteenth century in English. It was coined by Swedish chemist Torbern Bergman to refer to the compound NH3.

krypton

The chemical elements krypton, neon and xenon were all discovered in 1898 by the Scottish chemist William Ramsay and the English chemist Morris William Travers. All three are “noble” or “inert gases”. Krypton’s modern areas of application include fluorescent lighting, magnetic resonance imaging and computed tomography (CT scans).

For the naming of krypton, Ramsay suggested using the Ancient Greek adjective kruptos , meaning “hidden, secret, secluded” (as in cryptology). The ending in -⁠on either denotes the neuter singular form of the adjective, krupton , or represents, along with -⁠um, a typical suffixal ending for chemical elements (see, for example, boroncarbonsiliconargon and radon). The Ancient Greek adjective is itself a derivation of kruptein , meaning “to hide”, “cover” or “obscure”. Ramsay’s name choice likely referred to the scarcity of krypton in the Earth’s atmosphere. The Greek etymon kruptos can also be found in a twentieth-century neologism from the world of superhero comics, kryptonite.

kryptonite

Kryptonite was first described in the fictional world of the superhero Superman as a radioactive element from the planet Krypton (hence the element’s name), synthesized as the result of the planet’s radioactive explosion. Superman avoids all contact with the substance, as it neutralizes his powers. Therefore, since 1960, kryptonite is used, often with a hint of humour, to mean a weakness affecting someone’s strength, ability to think clearly, or resistance to temptation.

The exact source of inspiration for the name Krypton was not clearly explained by Superman’s creators Jerry Siegel and Joe Shuster, or any of their followers. It can reasonably be linked to the name of the noble gas krypton (from the Ancient Greek kruptos, meaning “hidden, secret, secluded”). The English words crypt and cryptic may also have played a role. The suffix -⁠ite denotes a mineral, and may recall kryptonite’s earliest status in the story as a meteorite.

The first attestation of kryptonite is not to be found in a written text, but in a June 1943 sound recording of the Adventures of Superman radio series, starring Bud Collyer as Superman/Clark Kent. The introduction of the substance in the storyline provided the hero with an Achilles’ heel showing obvious narrative benefits:

As [Superman] came within five feet of the mass of metal, which glowed like a green diamond, he suddenly felt weak, as if all his strength had been drained from him… Here was an enemy far more deadly than anything human. (From the 1943 script by George Lowther, quoted in Glen Weldon, Superman: The Unauthorized Biography.)

Kryptonite’s first printed attestation is officially found in a 1945 newspaper snippet commenting the latest episodes of the Superman radio show, but it took an additional four years for it to be mentioned in the comics. It finally was in a story aptly titled “Superman Returns to Krypton”, whose caption reads: “Superman has some unfinished business—the one remaining particle of Kryptonite on earth!” (Superman, issue no. 61, December 1949)
