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.

văcīvus or vŏcīvus (so always in Plautus; cf. Trin. prol. 11 Brix; Ritschl, Nov. Exc. I. p. 59 sq.), a, um, adj. [vaco], empty, void (ante-class.); absol.: aedes facere alicui, Plaut. Cas. 3, 4, 6: aedes aurium, id. Ps. 1, 5, 54; for which, aures, id. Cas. prol. 29; id. Trin. prol. 11.
With gen.: valens afflictet me vocivum virium, i. e. destitute of strength, powerless, Plaut. Bacch. 1, 2, 46: tempus laboris, Ter. Heaut. 1, 1, 38.
Adv.: văcīvē, at leisure, leisurely: libellum perlegere, Phaedr. 5, praef. 14.
