With respect to the text itself I have made this translation on the basis of the facsimile edition published by the Tenri Central Library in 1972 as part of its _Classica Japonica_ series. Ōtsuka Takanobu, _Koiyaado-cho Nihongo bunten_ (Tokyo, 1934) and its revised edition under the title of _Koriyaado Nihon bunten_ (Tokyo, 1957) have served as invaluable aids at every step of the translation. Ōtsuka's second edition is of invaluable scholarly importance because it contains a cross-reference to the Spanish manuscript from which Collado prepared the printed Latin edition as well as a concordance to the Japanese vocabulary.[41] This translation attempts to supplement Ōtsuka's invaluable contribution by relating the Latin text of this grammar with Rodriguez' _Arte_. _Editorial Conventions_ The Latin matrix of the text is printed in italic letters while the Japanese is in roman. For this translation I have reversed the convention. (In footnotes where the text is quoted the style of the original is followed.) In making editorial corrections in the Japanese material the corrected version is presented in brackets with periods to indicate the general location; e.g., _mairu mai queredomo_ [... qeredomo] (The only exception to this rule is the correcting of a missing open _o_, q.v.) Sentences that have been taken from the _Arte_ are indicated by the parenthetical recording of the leaf number of the citation immediately after the sentence; e.g., _xô tame no chôqui gia_ (22) 'it is.... Shorter sentences and specific words that in all likelihood have been taken from the _Arte_ are not listed if they are to be found in the section elsewhere noted as being the source of the material covered. Any {29} significant alteration in the form of the source is noted. Since the _Arte_ is numbered by the leaf, _v_ is added to the number to indicate the _verso_. All the corrections made by the _errata_ (on page 75 of the text) have been applied to the text without notation unless the correction is itself in error. The punctuation follows the text with the following exceptions; 1. In translating from Latin the English follows modern rules of punctuation. 2. Single quotes have been introduced into the text to mark glosses and translations. 3. In transcribing the Japanese citations any alteration of the original punctuation is noted. 4. The spacing of words in Japanese--a relatively casual matter in the text--has been regularized on the basis of the predominant pattern. 5. Two specific rules, based upon Collado's more or less consistent usage, are followed in the citing of verb forms: a. In the most frequent citation of verbs, where the root form is followed by the present indicative ending, a comma is used; e.g., _ari,u_; _ague,uru_; _mochi,tçu_ b. In an alternate form of citation, where the two forms are given in their entirety, a colon is used; e.g., _ari:aru_; _ague:aguru_; _mochi:motçu_
