Besides this, the suffix _cah_ accompanies all verbs in the present and imperfect; and the suffix _ah_ accompanies all transitive verbs through the remaining tenses, except the future. Present, 1st person, sing., _canan-in-cah_, I guard; imperf. 1st pers. sing., _canan-in cah cuchi_; perf., 1st pers. sing., _in canan-t-ah_. _In_ is the possessive pronoun, _cuchi_ the sign of the imperfect, _t_ in the perfect is a euphonic letter. The idea of transitive verbs is here taken somewhat narrower than usual. Only those are included which govern a word outside of themselves. All others are considered intransitive, even those which of themselves are active, but either have no expressed object (as, I love, I hate, etc.), or the word which they govern is in the verb itself, as in the Greek οικοδομεο, οικουρεω. As these can govern a second accusative, the object incorporated in the verb is included in the idea they express. The tenses of the intransitive verbs, except the present and imperfect, while they drop _ah_ and the possessive pronoun, are formed with that pronoun which forms sentences with a predicate. There are cases where not only the present omits _cah_, but where the stem, if it ends in _ah_ as is often the case, drops it, and substitutes _ic_. The signification then alters, and indicates an habitual action or quality. As _ic_ is the sign of the gerund, this change appears to be the transformation of the verb into a verbal, and to effect this, it must be united to that pronoun which serves as the substantive verb; _ten yacunic_, I love, properly, I am loving (habitually). What _cah_ and _ah_ mean by themselves, we are not informed. Where _cah_ is attached to the stem of some verbs it signifies intensity. _Ah_ is as a prefix the sign of the male sex, of the inhabitant of a place, and of names derived from active verbs. Hence it seems to have meant at first person, man, and later to have become a pronoun, and finally an affix. It is noteworthy that the same difference exists between _ah_ and _cah_, as between _en_ and _ten_. The _c_ may therefore be a radical sound. In the conjugation, _cah_ is treated wholly as a verb. For in this the possessive pronoun is always prefixed; and as in the present and imperfect it is placed after the stem of the verb and before _cah_, it is evident from the difference between the two forms _canan-in-cah_ and _in-canan-t-ah_, that in the former _cah_, and in the latter _canan_, are regarded as the verbs. _Canan-in-cah_ is precisely as the English “I do guard.”
