26. The short r

The short ṛ is found in every variety of word and of position, and is not rare, being just about as frequent as long ū. Long ṝ is very much more unusual, occurring only in certain plural cases of noun-stems in ṛ (371 b, d, 375). The ḷ is met with only in some of the forms and derivatives of a single not very common verbal root (kḷp).
