Vṛddhi

Vṛddhi itself has its origins in proto-vṛddhi, a process in the early stage of the Proto-Indo-European language originally for forming possessive derivatives of ablauting noun stems, with the meaning "of, belonging to, descended from".^[3] To form a vṛddhi-derivative, one takes the zero-grade of the ablauting stem (i.e. removes the vowel), inserts the vowel *e in a position which does not necessarily match that of the original vowel, and appends an accented thematic vowel (or accents any existing final thematic vowel). For example:^[1][4]

PIE *dyew- "sky" (cf. Latin diēs, Sanskrit dyú "day"; Hittite šīu- "god") → zero grade *diw- → proto-vṛddhi derivative *deyw-ó-s "god, sky god", lit. "skyling" (cf. Sanskrit devá, Latin deus, etc.)

However, in a later stage of the language this appears to have extended to non-ablauting noun stems that already contained *e, which would contract with the inserted vowel to form a lengthened *ē:^[1][4]

PIE *swéḱur-o- "father-in-law" (cf. Latin socer, Sanskrit śváśura) → proto-vṛddhi derivative *swēḱur-ó- "brother-in-law", lit. "male descendent of one's father in law" (cf. Sanskrit śvāśurá, Old High German swāgur "brother-in-law")

The above example also displays the stressing of the thematic vowel when it already exists. It is this later version of proto-vṛddhi which is displayed in Sanskrit's lengthened vṛddhi grade.^[1]

The general phenomenon of vowel gradation, including vṛddhi formation has been extensively studied and documented as part of Sanskrit's vigorous grammatical tradition, most importantly in the Aṣṭādhyāyī of the grammarian Pāṇini.^[5]

For example:^[6]

• bhṛ-tá- "carried" (zero grade)
• bhár-aṇa- "burden" (first grade, full grade, or guṇa)
• bhār-yá- "to be carried" (second grade, lengthened grade, or vṛddhi)

The full pattern of vowel gradation can be observed as follows:^[7]

In modern Indo-European linguistics it is used in Pāṇini's sense, but not restricted to Sanskrit but applicable to the Indo-European languages in general as well as to the Proto-Indo-European (PIE) language from which this feature was inherited:

• *bʰr̥-^[f] (zero grade of the reconstructed verb meaning "to carry")^[8]
• *bʰer- (full grade)
• *bʰēr- (vṛddhi, lengthened grade)
