dare-m, darē-s, dare-t, darē-mus, darē-tis, dare-nt; īre-m, fore-m, ferre-m. In verbs in -ere, the -rē- is preceded by a form ending in -e-: as, regere-m, capere-m; in verbs in -āre, -ēre, and -īre, by one ending in -ā-, -ē-, or -ī-, respectively: as, laudāre-m, monēre-m, audīre-m.
[850.] The suffix of the imperfect subjunctive of sum, am, is -sē-, which becomes -se- in some of the persons; esse-m, essē-s, esse-t, essē-mus, essē-tis, esse-nt; so also ēssē-s, &c. ([769]). volō, wish, nōlō, won’t, and mālō, prefer, have velle-m, nōlle-m, and mālle-m respectively ([166, 8]).
[851.] The future stem of sum, am, is ero|e-: erō, eri-s, eri-t, eri-mus, eri-tis, eru-nt. dō has dabō, eō has ībō, and queō has quībō.
[852.] (1.) The future stem of verbs in -ere and -īre ends in -a- in the first person singular, otherwise in -ē-, which becomes -e- in some of the persons: as,
rega-m, regē-s, rege-t, regē-mus, regē-tis, rege-nt; capia-m, capiē-s, &c.; audia-m, audiē-s, &c. The first person singular is not a future form, but the subjunctive present, used with a future meaning ([842]); forms in -em occur in manuscripts of Plautus: as, faciem, sinem. Verbs in -īre sometimes have -bo|e-, chiefly in the dramatists: as, scībō, opperībo-r (Plaut., Ter.), lēnību-nt (Prop.); rarely verbs in -ere ([819]): as, exsūgēbō (Plaut.). For reddibō, instead of the usual reddam, see [757].
[853.] (2.) The future stem of verbs in -āre and -ēre ends in -bo|e-, which is preceded by a form ending in long -ā- or -ē- respectively: as,
laudābō, laudābi-s, laudābi-t, laudābi-mus, laudābi-tis, laudābu-nt. monēbō, monēbi-s, &c.
