Reconstruction

The word is *luftuz in Orel and Wiktionary,[1][2] the stem *luftu- in Kroonen and Köbler,[3][4] and *luf-tu- in Bammesberger.[5]

Etymology

Wiktionary, following Kroonen, has it from Proto-Indo-European *lewbʰ- (“to peel, to break off, to damage”), from a PIE *lubʰ-tu-s.[2] Kroonen derives it from the root of *laubą "foliage", which he calls a European word with no clear PIE etymology.[3][6]

Morphology

A tu-stem, masculine in Kroonen,[3] feminine in Orel.[1] Bammesberger finds a feminine ti-stem *luf-ti- beside it, continued in Old English lyft,[5] and Orel takes the Old Norse word from *luftan.[1] EWA sets up *luftu-, *lufti- and *lufta-.[7]

Evidence

The word is attested in all three branches: Gothic 𐌻𐌿𐍆𐍄𐌿𐍃 (luftus) in Gothic, Old Norse loft in Old Norse, and Old English lyft, Old Frisian lufte, Old Saxon luft and Old High German luft in West Germanic.[3] Gothic has it in three passages of the Pauline epistles.[8] The Old Norse word passed into Middle English and Irish, and was borrowed as Finnish luhti (“upper storey”).[9]

Competing analyses

Kroonen thinks the original meaning was "roof", perhaps made of bark, comparing Russian луб (lub, “bast”) and Old Prussian lubbo (“bast, plank”), and rejects a link with the Hittite word for "sky".[3][2] Orel relates it to a Sanskrit verb "to break, to injure" and to Lithuanian lùpti (“to peel”), and allows the original meaning to have been "porch" or "upper floor", or else "air" seen as a section.[1] Köbler derives it, probably, from Pokorny's *lāip- "to shine, to burn",[4] Lehmann probably from PIE *lew- "to cut off", after Torp and Falk and Grienberger.[10] Feist found no sure comparisons,[11] and Casaretto calls the base word unknown, its labial continuing PIE b, bʰ or p.[12]

Meanings

  1. roof[3][4][2]
  2. firmament, heavens, sky[2]
  3. air, atmosphere[3][4][2]

EWA explains the word as properly "the sky as the upper ceiling", comparing Old English hūs-heofon (“ceiling of a room”).[7] In North Germanic only the sense "uppermost room of a building" survived, and "air, sky" is found only at the oldest stage;[7] de Vries glosses the Old Norse word "upper room in a house", also "air, sky".[9]

Derivatives
