Pronunciation

  • /taɪˈteɪni.əm/, /tɪˈteɪni.əm/[1]

Etymology

It is borrowed from German Titanium, the name given in 1795 by the German chemist Martin Heinrich Klaproth,[2][3][4][5] formed from Titan, titan, and -ium, -ium, after his earlier Uranium, uranium, following a pattern of names from Greek mythology.[2][6][7] Barnhart, Etymonline and Merriam-Webster describe it as a New Latin coinage.[4][3][8] Titan is Latin Tītān, from Ancient Greek Τιτάν (Titā́n), plural Τιτᾶνες (Titânes), the giants born of Uranus and Gaia.[2][7] Etymonline says the name rests on the fanciful notion of the Titans as "sons of the earth".[3] The French form titanium is also recorded in 1795.[2]

Earliest recorded meaning

The metallic element: 1796, in a paper by G. Pearson in the Philosophical Transactions of the Royal Society.[2][3][4]

Semantic evolution

The name was given to the element before it was obtained pure: a pure specimen was not isolated until 1887.[3] The word has kept its chemical sense;[2][8] since 1902 it has also been used attributively, of things made of titanium or a titanium alloy.[2] The metal is valued for being light, strong and resistant to corrosion, and is used especially in aircraft parts.[9][2]
