frustra

I In deception, in error (so mostly anteclass. and in historians; not in Cic. and Caes.): ambo, et servus et era, frustra sunt duo, Qui me Amphitruonem rentur esse: errant probe, are deceived, in error, Plaut. Am. 3, 3, 19; cf. id. Bacch. 4, 7, 42: nunc, mulier, nei frustra sies, mea non es: ne arbitrere, id. Merc. 3, 1, 30: quo mihi acrius annitendum est, ut neque vos capiamini, et illi frustra sint, Sall. J. 85, 6: frustra esse, Plaut. Capt. 4, 2, 74: hilarus est; frustrast homo, id. Most. 3, 1, 40 Lorenz: ne frustra sis, id. Men. 4, 3, 18 sq.; id. Mil. 5, 29 al.; cf. in the foll. II.

A. 13, 37; 51: si Persae frustra habitae redissent ad sua, Amm. 18, 6, 6: servom ac dominum, Plaut. Am. argument. 5.—

II Transf., according as particular respect is had to the effect, the aim, or the reason of an action, without effect, to no purpose, without cause, uselessly, in vain, for nothing (freq. and class.; the predom. signif. in prose and poetry; cf.: in cassum, nequiquam).

A Without effect, in vain: alii parasiti frustra obambulabant in foro, i. e. they got no dinner, Plaut. Capt. 3, 1, 31: praesagibat mihi animus, frustra me ire, quom exibam domo, id.

J. 7, 6 Kritz.; ib. 14, 11 Dietsch; 61, 1; 71, 5; 73 fin. al.; cf.: ita frustra id inceptum Volscis fuit, Liv. 2, 25, 2: neque frustrabor ultra cives meos, neque ipse frustra dictator ero, id. 2, 31, 10; Quint. 10, 1, 2: frustra cruento Marte carebimus, frustra metuemus Austrum: Visendus ater Cocytus, etc., Hor. C. 2, 14, 13 and 15: nam frustra vitium vitaveris illud, si te alio pravum detorseris, id. S. 2, 2, 54: tam frustra (expressere) quam recusaverat (= aeque frustra fuit et sine eventu), likewise without effect, Tac. H. 2, 90 fin. (see the passage in conn.).—With nequiquam, Cat. 77, 1; App. M. 8, p. 208, 40.—With sic: ego astabo hic tantisper cum hac forma et factis sic frustra; cf. Gr. ou(/tws a)/llws, Plaut. Mil. 4, 2, 30.—In a pun with frustra esse (v. supra, I.) and frustrari: qui lepide postulat alterum frustrari, quom frustra'st, frustra illum dicit frustra esse.

Com. 14, 41: quae disputatio ne frustra haberetur, id. Rep. 1, 7: quae (res) prima impulit etiam, ut suspiceremus in caelum nec frustra siderum motus intueremur, id. ib. 3, 2; 4, 3; id. Tusc. 1, 10, 21; id. Fin. 2, 12, 36; v.
