696. The root (by origin apparently a desiderative from √) accents irregularly the root-syllable in the weak forms: thus,  (but  etc. and  ÇB.).

697. A. The present-stem of the -class is made by adding to the root the syllable नु, which then in the strong forms receives the accent, and is strengthened to नो.

B. The few roots of the -class (about half-a-dozen) end in न्, with the exception of the later irregular कृ (or ) — for which, see below, 714. The two classes, then, are closely correspondent in form; and they are wholly accordant in inflection.

a. The of either class-sign is allowed to be dropped before  and  of the 1st du. and 1st pl. endings, except when the root (-class) ends in a consonant; and the before a vowel-ending becomes  or, according as it is preceded by one or by two consonants (129 a).

698. Examples of inflection: A. -class; root सु press out: strong form of stem, सुनो ; weak form, सुनु.
