398. Certain stems of this division

On the other hand, certain stems of this division, allowed by the grammarians a full inflection, are used to fill up the deficiencies of those of another form.

a. Thus, ásṛj n. blood, çákṛt n. ordure, yákṛt n. liver, dós n. (also m.) fore-arm, have beside them defective stems in án: see below, 432. Of none of them, however, is anything but the nom.-acc. sing. found in the older language, and other cases later are but very scantily represented.

b. Of ā́s n. mouth, and úd water, only a case or two are found, in the older language, beside āsán and āsyà, and udán and údaka (432).
