We come for his sake. Fugæ atque formidinis ergô non abituros. Liu. Eum donari virtutis ergô beneuolentiæque. Cic. Because of vertue, or for vertues sake.

I. With gen. (placed after it, like causa and gratia), in consequence of, on account of, because of (ante-class, but not in Plaut. or Ter.): quojus rei ergo, Cato R. R. 141, 2: hujus rei ergo, id. ib. 3; 4; ib. 139; Tab. Publica ap. Liv. 40, 52 fin.; 41, 28 fin.: dono militari virtutis ergo donari, S. C. ap. Liv. 25, 7; so, virtutis ergo, Lex ap. Cic. Opt.

Gell. 3, 8, 8: formidinis ergo, Lucr. 5, 1246: illius ergo, Verg. A. 6, 670.

II. Absol. (for cujus rei ergo), consequently, accordingly, therefore, then (class.): unus homo nobis cunctando restituit rem: ergo postque magisque viri nunc gloria claret, Enn. ap. Cic. de Sen. 4; Lucil. ap. Cic. Fin. 1, 3, 9; Plaut. Cist. 1, 1, 74: Polemoni et jam ante Aristoteli ea prima visa sunt, quae paulo ante dixi. Ergo nata est sententia veterum Academicorum, etc., Cic. Fin. 2, 11, 34: Albano non plus animi erat quam fidei, nec manere ergo, nec transire aperte ausus, etc., Liv. 1, 27; Verg. E. 5, 58 et saep.—The reason or cause sometimes follows with quia, quod: ergo istoc magis, quia vaniloquus, vapulabis, Plaut. Am. 1, 1, 222; cf. id. Mil. 4, 6, 18.—Ante- and postclass. pleonast.: ergo igitur, Plaut. Trin. 3, 3, 27; and: igitur ergo, App. M. 1, p. 104 al. —So in Ter. and Liv.: itaque ergo, Ter.

B. Transf.

1. In a logical conclusion, consequently, therefore: negat haec filiam me suam esse: non ergo haec mater mea est, Plaut. Ep. 4, 2, 20; Varr. L. L. 8, 47; 48; 49; 59 sq. al.: nullum dicere causae esse genus amentia est, etc.... Relinquitur ergo, ut omnia tria genera sint causarum, Cic. Inv. 1, 9 fin.: quis est enim, in quo sit cupiditas, quin recte cupidus dici possit? Ergo et avarus erit, sed finite, id. Fin. 2, 9, 27; 5, 9, 24: quis tam esset ferreus qui eam vitam ferre posset, etc.? Verum ergo illud est, quod a Tarentino Archyta dici solitum, id. Lael. 23, 88 et saep.; corresponding to igitur, id. ib. 14 fin. and 15 init.; so consecutively, igitur ... ergo ... ergo ... igitur ... id. N. D. 2, 21, 56 sq.—So with si, cum, quia, etc.: ergo ego nisi peperissem, Roma non oppugnaretur, Liv. 2, 40, 8; Plaut. Ep. 5, 2, 34; id. Capt. 2, 3, 63; id. Aul. 4, 10, 25. —So esp. in Cicero, like an (v. an I. D.), in interrogative argumentation, a minore ad majus, or ex aequo, so, so then: ergo haec veteranus miles facere poterit, doctus vir sapiensque non poterit? Cic. Tusc. 2, 17, 39; so with the future, id. ib. 41; 1, 14, 31; 3, 15, 31; id. Off. 1, 31, 114; id. Fin. 2, 33 fin.: ergo illi intelligunt, quid Epicurus dicat, ego non intelligo? id. ib. 2, 4, 13; cf. id.

2. In interrogations.

a. When an explanation is asked, do you say? do you mean? then: S. Quo agis? P. Quo tu? ... S. Quo ergo, scelus? Plaut. Pers. 2, 2, 23: Ipsus es? Ch. Ipsus Charmides sum. S. Ergo ipsusne es? id. Trin. 4, 2, 145; id. Ep. 1, 1, 19; Hor. S. 2, 3, 156.—

b. When a consequence is inquired for, Engl. then: Ps. lstuc ego jam satis scio. Si. Cur ergo, quod scis, me rogas? Plaut. Ps. 4, 1, 10: ergo in iis adolescentibus bonam spem esse dicemus, quos? etc., Cic. Fin. 2, 35, 117: dedemus ergo Hannibalem? dicet aliquis, Liv. 21, 10 fin. et saep.: num ergo is excaecat nos aut orbat sensibus, si? etc., Cic. Ac. 2, 23, 74; so, num ergo, Quint. 10, 1, 5; cf. id. 6, 3, 79: quid stamus? quin ergo imus? why not then? Plaut. Merc. 3, 3, 21; so, quin ergo, id. As. 1, 1, 15; 2, 2, 113; id. Merc. 5, 2, 88; id. Mil. 4, 2, 93.— Esp. freq., quid ergo? like the Gr. ti/ ou)=v, why then? but why? quid ergo hanc dubitas colloqui? Plaut. Mil. 4, 2, 17; cf. Cic. Fin. 4, 14; Ter. Phorm. 5, 7, 55; Tib. 3, 6, 51: quid ergo? hujusne vitae propositio Thyesten levare poterit? Cic. Tusc. 3, 18; id. Off. 3, 20, 81; 3, 15, 61; 3, 18, 73; id. Rosc. Am. 1, 2; id. Caecin. 20; id.

Ac. 2, 30, 96: desinite ergo, Caes. B. C. 3, 19 fin.: sequere ergo, Plaut. As. 2, 4, 83; id. Rud. 1, 2, 94; id. Stich. 5, 2, 20; cf.: amplectere ergo, id. Curc. 1, 3, 16: tace ergo, id.

4. Like igitur, in resuming an interrupted train of thought, as I was saying; I say, then; well then: tres viae sunt ad Mutinam, quo festinat animus, ut, etc.... Tres ergo ut dixi viae, Cic. Phil. 12, 9, 22; cf. id. Part. 13, 46; id. de Or. 1, 57; id. Top. 19, 73; id. Tusc. 1, 2, 4.—So (like igitur and inquam) after parenthetical sentences, Cic. Tusc. 1, 7, 14; id. Fin. 2, 34, 113; id. Fam. 15, 10, 1.—Less freq. for inquam in a mere repetition: mihi tuus pater, Pater hujus ergo, hospes Antidamas fuit, Plaut. Poen. 5, 2, 91; or in beginning a subject with reference to the expectation of the auditors (cf. Gr. a)/ra), then, now: accipite ergo animis, Verg. A. 10, 109; id. Cir. 29. See Hand Turs. II. pp. 440-467.
