4.) the future perfect, by changing i into ěro as fui fuero, amavi amavero, docui docuero, scripsi scripsero, memini meminero, cæpi cæpero, audivi audivero, &c. 3.) the pluperfect conjunctive, by changing i into issem as fui fuissem, docui docuissem, memini meminissem, scripsi scripsissem, audivi audivissem, &c. 2.) the pluperfect indicative, by changing i into ēram as fui fueram, amavi amaveram, docui docueram, scripsi scripseram, &c. Namely, 1.) perfect conjunctive : by changing the last letter i into ěrim with e short as amavi amaverim, docui docuerim, legi legerim, audivi audiverim, memini meminerim, fui fuerim, &c. From the perfect indicative are derived all perfects and pluperfects, with the future perfect, of the active voice. Since the gerunds are nothing more than parts of these participles in dus, we hence form the gerunds as amandum, di, do, &c.: docenī.
amantis, amandus: in the rest from ens entis as docens, docentis, docendus legens, legentis, legendus audiens, audientis, audien dus : whence we see, how from eo, iens, G. From the genitive of this participle we may form the future passive participle in dus by changing tis into dus as in the first conjugation amans, G. 5.) the present participle: from o, in the first conjugation, we make ans as amo amans: in the second, from eo ens as doceo docens : in the third and fourth, from o ens as lego legens, audio audiens. d) the present infinitive passive which always includes the imperfect: from e, in the first second and fourth conjugations we make i as amare amarī, docere docerī, audire audirī: but in the third ere is changed into i as legere legi. c) the present imperative passive: here there is no alteration it is exactly the same as the infinitive active as amare, &c. In the third conjugation four verbs reject e final as dic, duc, fac, fer, for dice, duce, face, fere.
b) the present imperative active by rejecting re as amā, docē, legé, audi. Hence a) the imperfect conjunctive, in the active by the addition of m, as amāre amārem, docēre docērem, legere legěrem, audire audirem, esse essem, posse possem, velle vellem : hence in the passive by changing m into r as amarer, docerěr, legerěr, audirer. 4.) the present infinitive active from o in the first conjugation we make āre, in the second ēre with e long, in the third ĕre with e short, and in the fourth īre with i long.
3.) the future indicative active: from o in the first conjugation we make ābo, in the second ēbo, in the third and fourth am as amabo, docebo, legam, audiam : add r to o, or change m into r, we have the future passive asĪmabor, docebór, legăr, audiăr. 2.) the imperfect indicative active: from o in the first conjugation we make ābam in the second, from eo ēbam in the others, from o ēbam as amabam, docebam, legebam, &c.: by changing afterwards m into r we have the imperfect indicative passive amabár, docebăr &c. Change o into or, and we have the present indicative passive and by changing m of em or am into r, or, what is the same thing, or into ěr and år, we have the present conjunctive passive of the same conjugations as amer, docear, &c. Namely, 1.) the present conjunctive active we form in the first conjugation by changing o into em, in the rest into am as, amo amem, doceo doceam, lego legam &c. From the present indicative are formed all other presents, and imperfects of the indicative, and, in a certain degree, of the conjunctive, and all futures, except the future perfect.
