Reconstruction

The adjective is *haitaz in Wiktionary,[1] *xaitaz in Orel,[2] and *haita- in Kroonen, Köbler and Heidermanns.[3][4][5]

Etymology

Wiktionary derives it from Proto-Indo-European *keHy- (“to be hot”), through a PIE *keHid-o-s.[1] Kroonen calls it an o-grade adjective *koid-o- formed within Germanic to a root *keid-, which has no certain cognate outside Germanic.[3]

Morphology

An adjective with the o-grade of the root.[3] Kroonen thinks the adjective and the inchoative Old Norse hitna (“to heat up”) imply a strong verb *hītan-, which is not attested.[3] EWA sees a derivative with the suffix *-ta- to the noun Old High German hei (“heat”),[6][7] and Heidermanns likewise a d-extension of the root *kai- "to burn" found in Old High German gihei (“heat”).[5]

Evidence

The adjective is attested only in North and West Germanic:[5] Old Norse heitr, Old English hāt, Old Frisian hēt, Old Saxon hēt and Old High German heiz.[3] Gothic has only the ablauting noun Gothic 𐌷𐌴𐌹𐍄𐍉 (heito, “fever”).[8][6]

Competing analyses

Heidermanns and de Vries see a t-extension of the same root in Lithuanian kaĩsti (“to become hot”),[5][9] but Kroonen calls this link wrong: the Lithuanian root kait- was borrowed from Germanic *haita-.[7] Bammesberger and Schubert set up a Gothic adjective *heits for the base of the Gothic noun, which Casaretto thinks less likely.[10][11]

Meanings

  1. hot[3][4][1]

Old English also used it for "excited, violent", and Old High German for "eager, ardent".[12][5]

Derivatives

  • *haitį̄ "heat",[13] Köbler's *haitī-.[14]
  • *haitijaną "to heat",[15] Orel's *xaitjanan, in Old Norse heita, Old English hǣtan and Old High German heizen.[16]
  • *haitēn "to become hot", in Old English hātian and Old High German heizēn.[17]
  • With the zero grade, *hitjō- "heat", in Old Saxon hittia and Old High German hizza.[18]

Reflexes

  • Old Norse: heitr (“hot”)[9]
  • Old English: hāt (“hot, burning, glowing”)[12]
  • Old Frisian: hēt (“hot, glowing, fierce”)[19]
  • Old Saxon: hēt (“hot, burning”)[20]
  • Old High German: heiz (“hot, glowing, burning, fiery”)[6]
  • Gothic has no form of the adjective.[5]
