The series of corresponding degrees is then as follows:

a. There is nowhere any occurrence of ṝ in a situation to undergo either guṇa or vṛddhi-change; nor does ḷ (26) ever suffer change to vṛddhi. Theoretically, ṝ would have the same changes as ṛ; and the vṛddhi of ḷ would be āl.

b. In secondary derivatives requiring vṛddhi of the first syllable (1204), the o of go (361 c) is strengthened to gāu: thus, gāumata, gāuṣṭhika.
