Augment (a)

A verbal S = [Pv] [K] A S^- is ‘augmented’ (a S) in the following way:

S = [Pv] K A S^-	>	a S = [Pv] a K A S^-	(1)
S = [Pv] A S^-	>	a S = [Pv] ^VA S^-	(2)

Note:

In the principal Paradigms augmented forms are denoted by a non-bold ‘a’ before the rest of the stem.

Examples:

[Pv] √	Impf/3/sg
	a^ThS^- a t
bhū ‘become’	abhavat
anusambhū ‘to be produced after’	anusamabhavat
iṣ ‘desire’	aicchat
udīṣ ‘rise, mount’	udaiṣat
