The royal grammar, commonly called Lylly's grammar, explained [electronic resource] : In those rules of it, which concern the genders, and irregular declinings of nouns; and the preterperfect tenses, and supines of verbs; ordinarily called, propria quæ maribus; quæ genus; and as in præsenti. By way of question and answer, opening the meanings of the rules with great plainness, to the understanding of children of meanest capacity. With choice critical observations on the same, from the best extant authors and grammarians; for the amending of the mistakes, and supplying the defects thereof. By William Walker, B.D. author of the Treatise of the English particles.
