VOWELS

THose Letters are called Vocales, Vowels, in pronouncing of which by the Instruments of Speech, the breath is freely emitted; and they are therefore stiled Apert or open Letters. These may be distin∣guished either, 1. Formally, by their several Apertions, and the man∣ner of configuration in the instruments of Speech required to the fra∣ming of them, which constitutes the distinct species of Vowels; or 2. Accidentally, by the quantity of time required to their prolation, by which the same Vowel is made either long or short.

There are (I conceive) eight simple different species of Vowels, easily distinguishable, whose powers are commonly used. I cannot deny, but that some other intermediate sounds might be found; but they would, by reason of their proximity to those others, prove of so difficult distinction, as would render them useless; these eight seem∣ing to be the principal and most remarkable periods, amongst the de∣grees of Apert sounds.

Also known as: svara-sandhi, ac-sandhi

Vowel sandhi is the name for sandhi changes between two adjacent vowels.

Here is a simple example of vowel sandhi:

Table of changes Generally, there are two ways we can describe sandhi rules:

The traditional approach is to study rules. This approach can be difficult at first. But over time, it helps us master all of sandhi's details.

The Western approach is to arrange these changes in a table or grid. This approach is simplistic and misses many details. But it is often easier for beginners to understand.

Each approach has its strengths and weaknesses. In this lesson, we will use both. To start, here is a table that shows the basics of vowel sandhi between two words:

a/ā i/ī u/ū ṛ/ṝ e ai o au
ā ya va ra e ' ā a o ' āva a
ā a ā ā ā a ā āvā ā
e ī vi ri a i ā i a i āvi i
e ī a ī ā ī a ī āvī ī
o yu ū ru a u ā u a u āvu u
o ū a ū ā ū a ū āvū ū
ar yṛ vṛ a ṛ ā ṛ a ṛ āvṛ
ar yṝ vṝ a ṝ ā ṝ a ṝ āvṝ
ai ye ve re a e ā e ave āve e
ai yai vai rai a ai ā ai a ai āvai ai
au yo vo ro a o ā o a o āvo o
au yau vau rau a au ā au a au āvau au

To use this table, find the first sound on the top row and the second sound on the right column. The corresponding cell in the table is the result. For example, if the first sound is i or ī and the second sound is ū, then the result is yū.

For details, read the rules below.

Similar vowels If the two vowels are similar, they combine and become long:

सीता अश्वम् इच्छति → सीताश्वम् इच्छति sītā aśvam icchati → sītāśvam icchati Sita wants a horse.

शबरी इषुम् इच्छति → शबरीषुम् इच्छति śabarī iṣum icchati → śabarīṣum icchati Shabari wants an arrow.

Dissimilar vowels If the two vowels are not similar, one of three things happens.

First: if the first vowel is simple and not a or ā, it becomes a semivowel:

Second: if the first vowel is a or ā, the two vowels combine and become a compound vowel:

But if the second vowel is ṛ, ṝ, or ḷ, it becomes a semivowel instead:

Third: if the first vowel is a compound vowel (e, ai, o, au), it becomes ay, āy, av, or āv, respectively:

These rules explain most of vowel sandhi. With a few more specific rules, we will have a nearly complete picture of vowel sandhi in Sanskrit.

Compound vowels at the end of a word At the end of a word, the compound vowels -e, -ai, and -o usually make extra changes.

Let's start with -ai since it changes in a more simple way. -ai becomes -ā when a vowel follows it. The idea is that -ai first becomes -āy, as we saw above. Then the y sound is dropped:

In these examples, note that tasyā ends with a vowel and the next word starts with a vowel. Does vowel sandhi happen again? No. tasyā does not combine further.

-e generally follows the same pattern as -ai. -e becomes -a in front of most vowels:

But if the second vowel is a, then -e doesn't change. Instead, the a disappears:

This change is similar to what happens in the combination aḥ + a. a disappears often in Sanskrit:

-o generally follows the same pattern as -e.

Vowels that don't use sandhi The vowels -ī, -ū and -e, if they are part of a word that uses the dual number, are never changed by sandhi:

Verb prefixes If a verb prefix ends with a or ā and the root starts with ṛ, the two combine to form ār instead of the usual ar:

visarga sandhi

visarga sandhi is the name for sandhi changes where the first sound is the visarga. Here is a simple example of visarga sandhi:

Many Sanskrit words end in the visarga, so visarga sandhi is very common.

Where does the visarga come from? The visarga itself comes from a sandhi change. s and r become the visarga when they appear at the end of a word:

Most of the visargas you hear and see will come from s. A very small number will come from r. If the visarga comes from r, its sandhi rules have some small differences. So it is important for us to know which sound the visarga comes from.

Table of changes Some learners find it helpful to see these sandhi changes in a table. So, here is a basic summary of visarga sandhi:

-as -ās -s -r
o ' ā r r a
a ā r r other vowels
o ā r r voiced consonants
āś ś ś c, ch
aṣ āṣ ṭ, ṭh
as ās s s t, th
aḥ āḥ other consonants

To use this table, find the ending of the word on the top row. Then find the second sound on the right column. The corresponding cell in the table is the result. For example, if the first term ends in -ās and the next one starts with c or ch, then the result is -āś.

Common changes Some changes are common and apply to all visarga sounds.

If the second sound is unvoiced, the visarga can become ś, ṣ, or s to match the second sound's point of pronunciation. Here are some examples:

These changes may even occur in front of śa, ṣa, and sa. But these changes are usually not written down:

-ās sandhi

If the visarga ends a term that originally ended in -ās, then it disappears if any voiced sound follows:

-as sandhi If the visarga ends a term that originally ended in -as, then it becomes o if any voiced consonant follows:

And if the second sound is a, then we replace all three sounds with o:

The ' symbol, which is called the avagraha, often shows that a vowel was removed due to sandhi.

Otherwise, the visarga disappears before other vowels, just as we saw with -ās above:

Other changes Otherwise, the visarga becomes r in front of any voiced sound:

But if the second sound is r, the visarga disappears and the vowel before it becomes long:

sa and eṣa The words saḥ (“he,” “that one”) and eṣaḥ (“he,” “this”) are very common in Sanskrit. They have their own unique visarga changes. But thankfully, those changes are simple. In front of a, they behave as you would expect:

But in front of all other sounds, the visarga disappears:
