146. The compound

The compound क्ष् kṣ is prescribed to be treated as simple ष् ṣ (not becoming क् k by 150, below). But the case is a rare one, and its actual treatment in the older language irregular.

a. In the only RV. cases where the kṣ has a quasi-radical character—namely anák from anákṣ, and ámyak from √myakṣ—the conversion is to k. Also, of forms of the s-aorist (see 890), we have adhāk, asrāk, arāik, etc. (for adhākṣ-t etc.); but also aprāṭ, ayāṭ, avāṭ, asrāṭ (for aprākṣ-t etc.). And RV. has twice ayās from √yaj, and AV. twice srās from √sṛj (wrongly referred by BR. to √sraṅs), both 2d sing., where the personal ending has perhaps crowded out the root-final and tense-sign.

b. The numeral ṣaṣ six is perhaps better to be regarded as ṣakṣ, with its kṣ treated as ṣ, according to the accepted rule.
