Vātika Prakrit: Less basic phonology
Before diving in, I have to admit that writing this in an engaging way was more challenging than I expected. Sandhi seems simple enough on the surface, but as I tried to lay it all out, I found myself grappling with a few tricky issues:
- I found it difficult to demarcate historical sound changes from those currently active in the language. What morphophonological changes are inherited from Old Indo-Aryan, which ones are the result of language contact and which ones are idiosyncratic, etc. The question of which changes are still active and which belong to the past is a bit blurry, and it complicates the decision of what to cover here and what to save for a post on diachronics.
- Secondly, the term "sandhi" should not become more of a catch-all term that it already is. Its exact scope can vary from language to language and it seems to encompass a multitude of processes, including assimilation, dissimilation, reduction and deletion, while also interacting with stuff like metathesis and floating segments. So, finding neat, generalized explanations that work for most cases was harder than expected.
- Personally, I don't really care to read a bunch of paragraphs filled with computationally precise lists of changes. It just doesn't make for a nice read. It's not as bad when the paragraphs are full of examples, but even with examples I don't know if any of this stuff makes for material that is both instructive and interesting.
In Vātika Prakrit, there are two primary applications of sandhi rules, which vary depending on the context in which the sound changes occur. Some rules apply in both cases. Internal sandhi occurs at the juncture of morphemes, members of compounds or between meaningful parts of words. These changes should be considered more historically significant. External sandhi on the other hand applies at word boundaries. These sound alterations frequently affect conjugation and declension paradigms, thereby adding complexity and increasing the potential for ungrammatical constructions. The orthography of Vātika Prakrit reflects changes caused both by internal and external sandhi.
There is another additional category of sound changes that fall outside of the definition of sandhi, as in they are purely allophonic in nature (in fact, they would have best been stated in the
first post on VP phonology). These sound alterations are not represented in the orthography. They include: the nasalization of vowels under influence of following coda nasals, affricates /tɕ, tɕʰ/ (rendered as <c, ch>) become [cç, cçʰ] in coda position, the approximant /ʋ/ (written as <v>) shifts to [w] when it follows a labial in initial consonant clusters.
Internal vowel Sandhi
In an effort to partition the sprawling
1 topic of sandhi and other sound changes into comprehensible chunks, it might be best to start with the type of euphonic processes that are triggered by vowel-vowel sequences (consonantal sandhi is for a later post). In Vātika Prakrit it can be generally stated that two vowels should not come into direct contact. That is to say, vowel hiatus is avoided. This is true without exceptions when it is word internally. To resolve hiatus word internally, Vātika Prakrit employs one of four strategies: elision, coalescence, glide formation and consonant insertion. Note that some of the possible vowel combinations are quite theoretical, and won't really occur in practice.
1. Elision
When two vowels clash, one of them is often sacrificed. This typically happens when one of the vowels is /ɨ/ (written as
u). For example,
a +
u simplifies to
a, and
u +
ē results in
ē. The same holds true for mid-tense vowels like
ē and
ō, which tend to overpower other vowels in the cluster. So,
ē +
o becomes
ē, and
i +
ō resolves into
ō. But, as with everything, there are exceptions: when
ē or
ō is followed by a lax
a, the result is a lax mid-vowel, yielding
e or
o. In more complex clusters like
ēā,
ēō, or
ōē, a consonant gets inserted (see point 4 below).
2. Coalescence
A common resolution for vowel hiatus is coalescence, where two adjacent vowels merge into one. The simplest coalescence, or at any rate the easiest to remember, occurs between like vowels, particularly the non-high tense-lax pairs. So, when two vowels of the same type (
a, ā,
e, ē, or
o, ō) come together, they typically form their tense counterpart:
ā,
ē, or
ō. For example,
amrā +
aḍavi =
amrāḍavi 'mango forest'. Unlike in Sanskrit, Vātika Prakrit doesn’t have neat high-vowel pairs. VP /ɨ/ has two sources, first the reduced OVP vowel *ə̯, but also combinations of high vowels and as a consequence, combinations like
i + ū,
ū + i, and
u + u all resolve into
u, rather than producing
ī or
ū. However, combinations of the same high vowels, like
i + i or
ū + ū, stay intact as
i and
ū. When
o or
ō meets
a or
ā, the result is usually
o, except in cases like
oa or
oā, which may coalesce into
ō. For sequences beginning with
e or
ē, the result is typically
ē.
Some combinations just have to be memorized, though. Notably,
ai/āi and
aū/āū typically become
e and
o, respectively.
3. Glide Formation
Another common strategy to resolve vowel hiatus is glide formation, in which the first vowel in the sequence is converted into a glide. This is particularly frequent when the initial vowel is high, such as
i or
ū. In such cases,
i becomes /y/ and
ū becomes /v/. For example, 'thus'
iti + 'indeed'
ē becomes
ityēva (and after further sound changes to
icēva). The lax vowels
e, o show similar behavior, but not as consistently. Also, remember that combinations like
i + ū or
ū + i resolve directly into
u, rather than an onglide.
4. Insertion
Not seldom, a consonant is inserted to avoid hiatus between two vowels. This inserted consonant can be one of the approximants (
v, l, r, y, w) or an alveolar (
n, t, d, s, z), depending on the phonological context or just plain convention. Once inserted, this consonant can undergo further phonological processes, making the range of actual sounds even greater.
External vowel sandhi
Fortunately, when it comes to vowel combinations at word boundaries, Vātika Prakrit is more forgiving, whereas Sanskrit or other Prakrits tend to be more restrictive. For now, the main principle governing external sandhi is simple: a word-final lax vowel can be dropped (apocoped?) if the following word starts with a tense vowel. We see this demonstrated in the example
drūbkh-imi ē-ti →
drūbkhim ēti 's/he goes in the fog'. In all other cases, a consonant is inserted to break the hiatus. This prothetic consonant is usually an approximant or an alveolar (see the above paragraph), though the specific consonant can vary and is not always predictable to me yet.
___________
1) By this point, the vowel sandhi system in VP is evidently quite a bit more straightforward than the natlangs I’m drawing from. Part of the reason is that
ē and
ō aren’t considered composite vowels like Sanskrit’s /ai/ and /au/. Sanskrit textbooks often discuss sandhi that affects the syllabic liquids under the header of Vowels. By the time of Old Vātika Prakrit, these had gained an inherent "supershort", yer-like vowel that was more centralised and shorter than other vowels. By the time of Scenic Vātika Prakrit these will drive some interesting apophonic mutations, but it's probably best to detail these with the other grades later on.
