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.

vae, interj. [οὐαί], an exclamation of pain or dread, ah! alas!

        1. (α) Absol.: Mantua, vae, miserae nimium vicina Cremonae, Verg. E. 9, 28; Hor. C. 1, 13, 3: vae verbero! Plaut. Mil. 2, 3, 51.
        2. (β) Very freq. like the Gr. οὐαί and our woe! with dat.: vae misero mihi! Plaut. Am. 2, 2, 94; Ter. Heaut. 2, 3, 9: mihi, id. Eun. 4, 4, 42: illi, Plaut. As. 2, 2, 7: tergo meo, id. Men. 2, 2, 3; cf. id. Capt. 3, 4, 117: capiti atque aetati tuae, id. Rud. 2, 3, 44.
          Esp., in the exclamation ascribed to Brennus: vae victis! intoleranda Romanis vox, Liv. 5, 48, 9; Flor. 1, 13, 17; Fest. p. 372 Müll.; Plaut. Ps. 5, 2, 19; also, as title of a Satire by Varro, v. Non. 82, 17; 156, 13; 492, 8 (Müll. de victis).
        3. (γ) Very rarely with acc.: vae te! woe to you! Plaut. As. 2, 4, 75: scelesta, vae te! Cat. 8, 15: vae me! Sen. Apocol. 4, 3.

2. vē- (sometimes vae-) [perh. = Sanscr. vi-in-, vi-dha-va; Lat. vidua; but cf. Curt. Gr. Etym. p. 3809, 135]; an inseparable particle denoting origin, out, which serves either to negative the positive idea lying in the simple word, or to strengthen a simple notion: vegrandis, small; vecors, senseless; vepallidus, very pale; ve-stigo, to search out; Vejovis, an anti-Jove; cf. Gell. 5, 12, 9 sqq.
