79. The prefixes or prepositions are called upasaggas in Pali. They
are sometimes prefixed to verbs and their derivatives.
Generally they modified the meaning of the root, or intensify it, and
sometimes alter it; in some cases they add nothing to the original
meaning of the root.
80. The prefixes are 20 in number, viz., aa, ati, adhi, anu, abhi,
apa, api, ava, u, upa, du, ni, nii, pa, paraa, pari, pati, vi, sa.m, su.
Examples
From the root kamU (to go) verb kamati (goes) is formed without adding
any prefix to it.
The following are formed with the prefixes:-
Prefix Root Verb Meaning
abhi + kamU = abhikkamati (goes ahead, proceeds)
pa.ti + kamU = pa.tikkamati (goes back, steps backwards, retreats)
apa + kamU = apakkamati (goes aside, deviates)
ati + kamU = atikkamati (goes beyond, surpasses)
aa + kamU = akkamati (treads upon)
pa + kamU = pakkamati (goes forth)
nii + kamU = nikkhamati (goes out)
upa + kamU = upakkamati (strives, plans)
sa.m + kamU = sa`nkamati (moves from one place to another)
paraa + kamU = parakkamati (strives, makes an effort)
anu + kamU = anukkamati (follows)
(noun from the same): anukkama (order)
The above examples show how these prefixes alter the meaning of a root.
