cp. Sk. āścarya since Upanishads of uncertain etym
■ The conventional etym. of Pāli grammarians connects it with accharā1 (which is prob. correct & thus reduces Sk. āścarya to a Sanskritisation of acchariya) viz. Dhammapāla: anabhiṇha-ppavattitāya accharāpaharaṇa-yoggaṃ that which happens without a moment’s notice, at the snap of a finger; i.e. causally unconnected (cp. Goth. silda-leiks in similar meaning) Vv-a.329; and Buddhaghosa: accharā-yoggan ti acchariyaṃ accharaṃ paharituṃ yuttan ti attho DN-a.i.43
