As for acquiescing in what a man understands not, or cannot reconcile to his reason, they know best the fruits of it that practice it. For my part, I'm a stranger to it, and cannot reconcile myself to such a principle. On the contrary, I am pretty sure he pretends in vain to convince the judgment, who explains not the nature of the thing. A man may give his verbal assent to he knows not what, out of fear, superstition, indifference, interest, and the like feeble and unfair motives: but as long as he conceives not what he believes, he cannot sincerely acquiesce in it, and remains deprived of all solid satisfaction. ... But he that comprehends a thing, is as sure of it as if he were himself the author.

Pāṇini had before him a list of irregularly formed words, which survives, in a somewhat modified form, as the Uṇādi Sūtra. There are also two appendixes to which Pāṇini refers: one is the Dhātupāṭha, "List of Verbal Roots," containing some 2000 roots, of which only about 800 have been found in Sanskrit literature, and from which about fifty Vedic verbs are omitted; the second is the Gaṇapāṭha, or "List of Word-Groups," to which certain rules apply. These gaṇas were metrically arranged in the Gaṇaratna-mahodadhi, composed by Vardhamāna in 1140 A. D.

The various structures of sentences in any given language, comprising for example at least two nominal pieces and a verbal piece must be collated, and such categories as voice, mood, affirmative, negative, tense, aspect, gender, number, person and case, if found applicable and valid in descriptive statement, are to be abstracted from, and referred back to the sentence as a whole.
