The concept itself, along with the rest of the vowel gradation processes, has its origin in an early stage of the Proto-Indo-European language.
Vṛddhi in SanskritEdit
The general phenomenon of vowel gradation, including vṛdhhi formation has been extensively studied and documented as part of Sanskrit's vigorous grammatical tradition, most importantly in the Aṣṭhadhyayī of the grammarian Pāṇini.
- bhṛ-tá- "carried" (zero grade)
- bhár-aṇa- "burden" (first grade, full grade, or guṇa)
- bhār-yá- "to be carried" (second grade, lengethened grade, or vṛddhi)
The full pattern of vowel gradation can be observed as follows:
|Zero grade||← 1st grade →||2nd grade|
Vṛddhi in Indo-EuropeanEdit
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:
A vṛddhi-derivation or vṛddhi-derivative is a word that is derived by such lengthening, a type of formation very common in Sanskrit, but also attested in other languages. Such derivatives signify "of, belonging to, descended from". An example:
- PIE *swéḱuro- "father-in-law" (Vedic Sanskrit śváśura-) → *swēḱuró- "relating to one's father-in-law" (Vedic śvāśura- "relating to one's father-in-law", Old High German swāgur "brother-in-law")
Derivatives that are formed by inserting a full grade (as opposed to a lengthened grade) vowel into the "wrong" position of a zero grade are also called vṛddhi-derivations:
