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 are recognized in [Pāṇini|]'s [Ashtadhyayi|] at 1.4.58-59, and are enumerated in the [Pāṇini#Gaņapāțha|] :
- ati- "beyond"
- adhi- "over"
- apa- "away"
- api- "proximate"
- abhi- "to, towards"
- anu- "after"
- ava- "off, down"
- āṅ- "near"
- ut-/ud- "up"
- 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"
