Word History

Etymology

Noun (1)

Middle English asshe, from Old English æsc; akin to Old High German ask ash, Latin ornus mountain ash

Noun (2)

Middle English, usually as plural asshen, askes, axen, ashes, going back to Old English axe, asce (feminine weak noun), going back to Germanic *askōn- (whence also Old Saxon asc-, in ascal "ash-colored," Old High German asca, ascha "ash," Old Norse aska) beside apparent *azgō in Gothic azgo "ash," both of uncertain origin

Note: The older handbooks see the Germanic etymon as a "root extension" of a verbal base *ā̌s- "burn," in current laryngealist terms *h₁eh₂s-,*h₂h_̥1s- "make dry through heat" ("[durch Hitze] vertrocknen" in Lexikon der indogermanischen Verben)—see etymology and note at arid. The discrepancy between West and North Germanic ask- (from *azg-?) and Gothic azg- (from *azg^h-?) is variously explained. E. Seebold (Etymologisches Wörterbuch der deutschen Sprache, 22. Auflage) regards the velar extension as a suffix of appurtenance, the ashes being in effect "what belongs to the hearth/fire." (Also of relevance would be Armenian azazim "become dry, wither," if from *h₂h_̥1s-g^h- —see H. Martirosyan, Etymologial Dictionary of the Armenian Inherited Lexicon, Brill, 2010 s.v.) Seebold sees the "ash" words with long vowels (Hittite ḫāšš- "ashes, dust," Sanskrit ā́saḥ) as parallel derivations, in this case by the employment of lengthened grade. The inconvenient Gothic word azgo is explained as the outcome of a suffixed verbal derivative *haz-d-ko- (on the verbal derivative see azalea). Departing completely from the root-extension hypotheses, G. Kroonen (Etymological Dictionary of Proto-Germanic, Brill, 2013) sees the Germanic word as a possible compound of Indo-European *h₂ed- "dry up" and *d^heg^wh- "burn."
