Word History

Etymology

borrowed from French & Latin; French aride, going back to Middle French, borrowed from Latin āridus, ārdus "dry, waterless, withered, austere (of style)," derivative, with the adjective suffix -idus, of ārēre "to be dry, parched, withered," going back to Indo-European *h₂eh₁s-eh₁-, stative derivative of a verbal base *h₂eh₁s- "make dry with heat," whence also Tocharian A asatär "(it) dries up," Tocharian B osotär; also from the same base a root noun *h₂eh₁s-, whence Hittite ḫāšš- "ashes, dust," from which as thematic derivatives Sanskrit ā́saḥ "ashes, dust," and (as a collective or noun of appurtenance?) *h₂eh₁s-eh₂-, whence Latin āra "altar," Oscan aasaí (locative), Hittite ḫāššā- "hearth," Old High German essa, esse "forge" (from *asjō-), Old Swedish æsia, æssia "smith's fire," Old Icelandic esja "soapstone (used in hearths)" (both from *asjōn-)

Note: Regarding the apparent derivatives ardēre "to burn, emit light or flame" and ardor "burning, fierce heat," see ardent. — Lexikon der indogermanischen Verben gives the "essive" (= stative) form of the verbal base *h₂eh₁s as *h₂h₁s-h₁i̯é- and attributes the length in Latin ārēre to the influence of noun derivatives such as āra. D. Adams, however, regards the original base in Tocharian A and B to have been *ās-, corresponding to the length in the Latin verb (see A Dictionary of Tocharian B, Revised and Greatly Enlarged, Rodopi, 2013, p. 63). A. Kloekhorst (Etymological Dictionary of the Hittite Inherited Lexicon, Brill, 2008, pp. 322-23) regards the short vowel in Germanic as the residue of an oblique case form *h₁h₂s- of the root noun.
