Chapter III Passive Forms

64. (a) Only Transitive verbs can have passive forms. Very often the Intransitive roots become Transitive by means of the prefixes joined to them, then they also may have the passive forms.

The ways of constructing the passive forms and the rules of assimilation are stated in §§82, 83. [N.P.C.ii]*

(b) The conjugational signs given for the various groups of the roots are useless here. Ya stands as the only passive conjugational sign for every group.

(c) Two groups of personal endings named 'Parassapada' and 'Attanopada' are given above. The later group, which may be called 'Reflexive', was at first used only for the Passive Voice; but later on the distinction disappeared and both the groups were used in either Voice.**
