ḷ and ḻ
Here, we will study some of the rarer sounds in Sanskrit. We will also study a special Vedic consonant.
ḷ and ḹ
ḷ is the fifth and final short vowel. ḷ is pronounced in many different ways, and the best advice I can give you is to take your best guess. Some common pronunciations are li and lri.
ḷ appears in a single verb root: kḷp (kalpate). The verb has many meanings, including "be ready for," "happen," "prepare," "cause," "create," "declare," "help somebody in obtaining something," and "perform." As far as I know, it occurs nowhere else in the Sanskrit language.
If ḷ, is rare, ḹ is even rarer: it appears in no Sanskrit works at all! ḹ is an "artificial" sound that the old Sanskrit grammarians invented, probably to create a parallel to ṝ.
ḷ follows the pattern of ṛ.
The consonant ḻ occurs in Vedic Sanskrit only. ḻ is an alternate version of ḍ, and it is used only when ḍ appears between two vowels. Likewise, ḍh becomes ḻh.
Both of these consonants are retroflex consonants.
