English has two main words spelled hex: a verb and noun of witchcraft, borrowed from Pennsylvania German in the 19th century, and a computing word, a shortening of hexadecimal from the 1970s.[1][2][3][4]

Pronunciation

hex1 to bewitch; a spell

Etymology

The verb meaning to bewitch is borrowed from Pennsylvania German hexe (“to practise witchcraft”),[1][6][7][2][8] from German hexen (“to bewitch”),[1][6][9] which is related to Hexe (“witch”).[6][7] The German noun goes back to Middle High German hecse, also hexse,[6][9] from Old High German hagazussa, which the American Heritage Dictionary gives as hagzissa;[6][9] it is related to English hag.[1][7][3] Wiktionary compares Dutch heks (“witch”), beheksen (“to bewitch”) and Old English hægtesse (“witch, hag”).[5] Merriam-Webster derives the transitive verb from the compound verhexe, formed with ver-, the counterpart of English for-.[2] The noun, first meaning a witch, is likewise from Pennsylvania German, after the German noun.[1][10][8][4]

Earliest recorded meaning

To practise witchcraft: 1830, in J. F. Watson's Annals of Philadelphia,[1][2] an American word, as Barnhart and Etymonline note.[7][6] Dictionary.com dates the word to 1820–30.[11]

Semantic evolution

The word stayed chiefly North American.[10][4] The verb was first intransitive, to practise witchcraft, and then also transitive, to bewitch or put a spell on someone;[1][2] the Shorter Oxford dates the transitive use only to the mid 20th century.[10] The noun at first meant a witch (1856), also a woman who looks like one; the sense "magic spell, curse" is recorded from 1909, in the Saturday Evening Post.[1][6][7] Today the noun usually means a spell that brings bad luck, or something or someone that does,[9][2] and the verb has the weakened sense of bringing or wishing bad luck on something.[9]

hex2 hexadecimal

Etymology

The computing word is a clipping from English hexadecimal,[1][2][3][4][10] which is formed from English hexa- + decimal.[6] Merriam-Webster takes hexadecimal as an alteration of sexadecimal under the influence of hexa-.[2]

Earliest recorded meaning

Hexadecimal, as a noun or adjective: Merriam-Webster dates this use to 1970,[2] the OED to 1975, in the IBM Technical Disclosure Bulletin.[1]

Semantic evolution

Hexadecimal itself is older: the adjective is recorded from 1954 (Etymonline gives 1952) and the noun, the hexadecimal system, from 1970.[1][6] The short form is used both as a noun and before another noun, as in hex code.[3][1]

Timeline

  • 1970 – hexadecimal notation.[2] The OED's first quotation is from 1975.[1]

Meanings

Usage notes

Several minor words are spelled the same way: hex as short for hexagonal, as in a hex head bolt, recorded from 1924;[2] in nuclear physics, hex for uranium hexafluoride, from 1956;[1][10] and in rock climbing a hex, a six-sided metal nut, short for the trade name Hexentric, from 1982.[1]
