Pali iṭṭhakā (itthakā) (1)
According to Davids and Stede’s Pali-English Dictionary, Pali word iṭṭhakā (itthakā) refers “to a burnt brick and a tile.” It is linguistically related to Sanskrit idhma (firewood), inddhe (to kindle), edhaḥ (fuel); Greek ἀίϑω (aítho), αἷϑος (aíthos); Latin aedes, aestas, aestus; and Avesta ištya (tile, brick). It traces its origin to the Tamil root iṭṭu through the transformation of iṭṭu > ishṭaka > iṭṭhakā (itthakā).
