- bhṛ-tá- 'carried' ("base form", nowadays called zero grade)
- bhár-aṇa- 'burden' (guṇa, full grade)
- bhār-yá- 'to be carried' (vṛddhi, lengthened grade)
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- (zero grade of the reconstructed verb meaning 'to carry')
- *bʰer- (full grade)
- *bʰēr- (vṛddhi, lengthened grade)
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')
- in Sanskrit, a -tí-nomen actionis formed from the verbal root vṛdh-/vardh- 'to grow'
- *werdʰ- 'to grow' entry at Indo-European etymological database of The Tower of Babel project

- The asterisk * indicates that this form is not directly attested, but has been reconstructed on the basis of other linguistic material.
