and _Mume_ written for _Vme_ in order to conform more closely to its pronunciation.[18] Also _Mu_ is written for _Bu_[19] so that all the harmony _(armonia)_ in the formations of this language are contained in the rules for _Goyn_ and _Canadzucai_. Those who are informed see, as native speakers, how the tenses are formed for any mood, and which letter, or syllable, must be changed to another to affect a formation. Concerning this matter there is a booklet[20] which teaches _Canadzucai_, and the general rules on the subject. Teachers should have this booklet to teach more easily and advantageously those students who are learning _Cana_. Lacking a knowledge of _Goyn_ and _Canadzucai_, some of the rules which until now have been used in the formation of verbs (some of which I have let remain as they were), are not the original and natural rules as are the _Goyn_.[21] They are rather devices, some forming affirmative tenses and moods from negative forms and others forming them from yet other more remote sources, which appear to correspond to formational rules, but for which the proper rules are not known. The fact is that the affirmative as well as negative are formed from the affirmative, beginning with the root, as will be seen below._ _Speaking in general of the formation of the verb, the forms of the indicative and imperative moods of all three conjugations are formed from the root of the verb. The rest of the tenses in the other affirmative moods are formed from either the indicative or imperative forms. In the same way, the negative indicative present is formed from the root of the verb and the other tenses of the indicative are formed from {17} the present form. The other negative moods are formed from the indicative forms._ FORMATION OF THE TENSES FOR THE INDICATIVE AND IMPERATIVE MOODS OF THE VERBS OF THE FIRST AFFIRMATIVE CONJUGATION _The final syllables of the roots of the first affirmative conjugation, by which the verbs conjugated here are known, and from which the tenses of the indicative will be formed, end in _E_, with the exception of the verb "to do," _Xi_, or _Ii_, with its compounds and certain other verbs which end in _I_. The verbs which belong to the first conjugation, are as follows [in Charts A & B]._ _The verb _Xi_ "to do," with its compounds ending in _Xi_ or _Ii_, follows the formation of the verbs of the first conjugation. _Ii_ is _Xi_ which has been changed _(alterado)_ to _Ii_ because it follows the letter _N_. _Xi_ conforms to the rules for the syllables which are changed _(se mudam)_ to others.
