[769.] edō, eat, has a present system with a formative vowel like regō throughout ([782]); but in some parts of the present, and of the imperfect subjunctive, parallel root forms are usually found, with d of the root changed to s, and the vowel lengthened ([135]), as may be seen in the following:

[770.] For ēs, see [728]; for edim, &c., [841]. In the passive, the indicative present ēstur is used, and imperfect subjunctive ēssētur. The perfect participle ēsus is for an older ēssus ([170, 7]). Supines ēssum, ēssū (Plaut.).

The participle perfect is comēssus, comēsus, or comēstus, future comēssūrus. exedō, eat out, has exēst and exēsse; subjunctive exedint. adedō, eat at, has adēst.

[772.] volō (nōlō, mālō) and ferō have the bare root in some parts only of the present system; in other parts the root extended by a formative vowel, like regō ([782]). volō (nōlō, mālō) lack some forms, as will be seen below.

[774.] volo for volō is rare ([2443]). volt and voltis became vult and vultis about the time of Augustus ([141]). For volumus, see [142]; velim, &c., [841]; vellem, &c., velle, [166, 8]. sīs, an thou wilt, is common for sī vīs (Plaut., Ter., Cic., Liv.). sultis, an ‘t please you, is used by Plautus for sī voltis.

[775.] nōlō, won’t, is formed from ne-, not, and volō, juxtaposed, and mālō, like better, abbreviated from māvolō for *magsvolo ([779], [170, 2]).
