- Source: Upasarga
Upasarga is a term used in Sanskrit grammar for a special class of twenty prepositional particles prefixed to verbs or to action nouns. In Vedic, these prepositions are separable from verbs; in classical Sanskrit the prefixing is obligatory.
The twenty prefixes (in Indic alphabetical order) are recognized in Pāṇini's Aṣṭādhyāyī at 1.4.58-59, and are enumerated in the gaṇapāṭha (#154):
ati- "beyond"
adhi- "over"
apa- "away"
api- "proximate"
abhi- "to, towards"
anu- "after"
ava- "off, down"
āṅ- "near"
ut-/ud- "up(wards)"
upa- "towards, near"
dus-/dur- "bad, difficult, hard"
ni- "down"
nis-/nir- "away"
parā- "away"
pari- "round, around"
pra- "forth"
prati- "against"
vi- "apart, asunder"
sam-/saṃ- "with"
su- "good, excellent"
By the usual rules of euphonic combination the two prepositions ending in visarga, niḥ and duḥ, have the alternative forms nis-/nir- and dus-/dur- respectively. The gaṇapāṭha listing has these variants, not the forms in pausa, and thus has twenty-two items in all.
A versified form of this list may be found in modern primers or textbooks:
