Lewis & Short

Parsing inflected forms may not always work as expected. If the following does not give the correct word, try Latin Words or Perseus.

aut, conj. [aut, Osc. auti, Umbr. ote, ute, may be a modification of autem, as at of et, the suffix -t being a relic of the demonstrative -tem, which appears in item, and is the same as -dem in quidem, and -dam in quondam, and of which the demonstrative adverbs, tam and tum, are absolute forms; the first part of these words may be compared with the Gr. αὖ (cf. αὖτε and αὐτάρ), and with the Sanscr. vā = or, with which again may be compared ve and vel; v. Corss. Ausspr. II. p. 595, and also pp. 130, 223, 411], or; and repeated: aut … aut, either … or; so in Sanscr. vā … vā.

  1. I. In gen. it puts in the place of a previous assertion another, objectively and absolutely antithetical to it, while vel indicates that the contrast rests upon subjective opinion or choice; i. e. aut is objective, vel subjective, or aut excludes one term, vel makes the two indifferent.
        1. a. Used singly, or: omnia bene sunt ei dicenda, qui hoc se posse profitetur aut eloquentiae nomen relinquendum est, Cic. de Or. 2, 2, 5: quibusnam manibus aut quibus viribus, Caes. B. G. 2, 30: Vinceris aut vincis, Prop. 2, 8, 10: cita mors venit aut victoria laeta, Hor. S. 1, 1, 8: ruminat herbas aut aliquam in magno sequitur grege, Verg. E. 6, 55 et persaep. (cf. on the contrary, Tac. G. 8: quae neque confirmare argumentis, neque refellere in animo est: ex ingenio suo quisque demat vel addat fidem).
        2. b. Repeated, aut … aut, either … or: Ubi enim potest illa aetas aut calescere vel apricatione melius vel igni, aut vicissim umbris aquisve refrigerari salubrius? Cic. Sen. 16, 57: Nam ejus per unam, ut audio, aut vivam aut moriar sententiam, Ter. Phorm. 3, 1, 19; id.

Ac. 2, 30, 96: partem planitiae aut Jovis templum aut oppidum tenet, Liv. 44, 6, 15: terra in universum aut silvis horrida aut paludibus foeda, Tac. G. 5: hoc bellum quis umquam arbitraretur aut ab omnibus imperatoribus uno anno aut omnibus annis ab uno imperatore confici posse? Cic. Imp. Pomp. 11,31.

More than twice repeated: aut equos Alere aut canes ad venandum, aut ad philosophos, Ter And. 1, 1, 29: Uxor, si cesses, aut te amare cogitat Aut tete amare aut potare atque animo obsequi, id. Ad. 1, 1, 7 sq.; so four times in Lucr. 4, 935 sq.; five times in Cic. Off. 1, 9, 28; id. N. D. 3, 12, 30; and Prop. 4, 21, 26 sqq.; and six times in Plin. 17, 10, 9, § 58.
        4. d. Sometimes double disjunctive phrases with aut … aut are placed together: Adsentior Crasso, ne aut de C. Laelii soceri mei aut de hujus generi aut arte aut gloriā detraham, Cic. de Or. 1, 9, 35: res ipsa et rei publicae tempus aut me ipsum, quod nolim, aut alium quempiam aut invitabit aut dehortabitur, id. Pis. 39, 94.
        5. e. Repeated after negatives: ne aut ille alserit Aut ceciderit atque aliquid praefregerit, Ter. Ad. 1, 1, 11: ne tanti facinoris immanitas aut exstitisse aut non vindicata esse videatur, Cic. Cat. 1, 6, 14; id. Sull. 43; id. Sest. 37; 39: neque enim sunt aut obscura aut non multa post commissa, id. Cat. 1, 6, 15; id. Off. 1, 20, 66; 1, 11, 36; 1, 20, 68; id. de Or. 2, 45, 189: nec milites ad scelus missos aut numero validos aut animo promptos, Tac. A. 14, 58; id. H. 1, 18; id.

Caes. 58; id. Ner. 34: Nec aut Persae aut Macedones dubitavere, Curt. 4, 15, 28: Non sum aut tam inhumanus aut tam alienus a Sardis. Cic. Scaur. 39; id.

        6. f. In interrogations: quo modo aut geometres cernere ea potest, quae aut nulla sunt aut internosci a falsis non possunt aut is, qui fidibus utitur, explere numeros et conficere versus? Cic. Ac. 2, 7, 22; so id. de Or. 1, 9, 37; id. Rosc. Am. 40, 118; id. N. D. 1, 43, 121.
        7. g. In comparative clauses: talis autem simulatio vanitati est conjunctior quam aut liberalitati aut honestati, Cic. Off. 1, 15, 44.

Hec. 4, 4, 76: id (principium) nec nasci potest nec mori, aut concidat omne caelum etc., Cic.

          In this signification aut sometimes begins a new clause: Potestne igitur quisquam dicere, inter eum, qui doleat, et inter eum, qui in voluptate sit, nihil interesse?
