In order to indicate the differences to be found between the descriptions presented by Rodriguez and Collado, I have extracted the formational rules from the _Arte Breve_ and, setting aside only two short appendices dealing with variant forms, present them here in their entirety.
_THE CONJUGATION AND FORMATION OF THE TENSES AND MOODS OF THE VERBS_
_All the verbs of this language may be reduced _(se reduzem)_ to four affirmative and three negative conjugations. This is because the negative conjugation of the adjectival verb, which we discussed before,[11] agrees with the second of the three conjugations; and the conjugation of the substantive verb _S[vo]rai_, _S[vo]r[vo]_, or _soro_, which is an abbreviated form of _Samburai_, _sambur[vo]_[12] both in the affirmative and the negative is reduced to the third conjugation. At this point we will treat the three affirmative and three negative ordinary conjugations of the regular personal verbs.[13] Following this, and on account of its particular usage and formation, we will discuss the conjugation of the adjectival verb._
_The verbs of this language do not change _(naõ f[~e] variedade)_ to show person and number as do those of Latin; rather, one form _(voz)_ { 15} is used for all persons, singular and plural. Number and person are understood according to the subject _(Naminativo [_sic_])_, or pronoun, which is joined to the verb. The moods of the verb, which in this language have distinct forms for the tenses, are indicative, imperative, conjunctive, conditional, and preterit participle. The remaining moods are made up of these forms joined to certain particles. Each mood has but three tenses which have distinct forms; these are preterit, present, and future. These forms are signified by the Japanese terms _(vocabulos)_ _Quaco_, _ghenzai_, _mirai_. The preterit imperfect and pluperfect are made up of the present, preterit, and preterit participle together with the substantive verb, as will be seen below in the conjugations._
